== Glossaire ==
This guide covers [[Special:MyLanguage/Troubleshooting|connection issues]] with [[Special:MyLanguage/VRChat|VRChat]]. Connecting to VRChat requires a reliable path to Cloudflare, AWS CloudFront, and Photon Engine.<ref name="vrc-conn">{{VRC link|https://help.vrchat.com/hc/en-us/articles/360062658433-Troubleshooting-Connection-Issues-with-VRChat|Troubleshooting Connection Issues with VRChat}} on ''help.vrchat.com''.</ref> Check VRChat's official status outlets before changing local network settings.
Ce guide contient une terminologie concernant les ordinateurs, et utilise souvent les abréviations suivantes

If the status outlets above do not show an incident, some users change DNS, prefer IPv4 over IPv6, or use Cloudflare WARP. This guide treats DNS as the first local change. Disabling IPv6 is not recommended on Windows, and it can remove Internet access on IPv6-only ISPs.<ref name="ms-ipv6">[https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/configure-ipv6-in-windows Configure IPv6 for advanced users] on ''learn.microsoft.com''.</ref>

==== Économie des créateurs et achats ====
<div lang="en" dir="ltr" class="mw-content-ltr">
L'[[Special:MyLanguage/Creator Economy|économie des créateurs]] de VRChat dépend des services de Thunes, anciennement Tilia, pour effectuer les transactions et vérifier les informations d'achat entre les utilisateurs et les vendeurs.
On IPv6-only networks, use the provider's IPv6 DNS addresses. Cloudflare and Google both publish IPv6 resolver addresses.<ref name="cf-ips" /><ref name="google-dns" />
</div>


* Thunes (anciennement Tilia)
<div lang="en" dir="ltr" class="mw-content-ltr">
Use first-party setup pages. VPN or security apps sometimes document their own resolver addresses; use those only if you mean to use that vendor's DNS. Otherwise use Cloudflare, Google, or another provider from the table below.

===Option 1 - Utiliser un tunnel VPN===
<div lang="en" dir="ltr" class="mw-content-ltr">
Si vous rencontrez des problèmes de connexion, il peut être intéressant d'utiliser un tunnel VPN afin de stabiliser celle-ci. Notez qu'utiliser un VPN qui masque votre adresse IP ou modifie votre emplacement géographique virtuel peut entraîner des erreurs et causer des déconnexions fréquentes.
Cloudflare 1.1.1.1 addresses:<ref name="cf-ips" />
 
<syntaxhighlight lang="text">
# [https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/ WARP par Cloudflare] est un tunnel VPN qui aide à stabiliser votre connexion et crypte votre trafic en utilisant les serveurs de Cloudflare, ce qui peut aider à régler vos problèmes de connexion dans VRChat.

## [https://developers.cloudflare.com/1.1.1.1/setup/ 1.1.1.1 by Cloudflare] est un résolveur DNS alternatif inclut avec Warp. Il est conçu pour assurer la sécurité et confidentialité en cryptant une partie du trafic de votre appareil.
 
===Option 2 - Configurer un serveur DNS.===
*'''Windows10''' : https://docs.quad9.net/fr/Guides_de_configuration/Windows/Windows_10/
*'''Windows11''' : https://docs.quad9.net/fr/Guides_de_configuration/Windows/Windows_11_%28Crypt%C3%A9%29/
*'''Mac''' : https://docs.quad9.net/fr/Guides_de_configuration/MacOS/Big_Sur_et_plus_r%C3%A9cent_%28Chiffr%C3%A9%29/
*'''Linux''' : https://docs.quad9.net/fr/Guides_de_configuration/Linux_et_BSD/Ubuntu_22.04_%28Chiffr%C3%A9%29/
 
Les guides des paramètres DNS ci-dessus utiliseront par défaut les adresses IP qui se connectent au serveur DNS « Quad9 ».
À la place, utilisez l'adresse IP fournie par Cloudflare.
 
'''Vous devez inclure les paramètres de l'IPv4 et IPv6 pour le faire fonctionner sans problèmes'''

=== Cloudflare WARP ===
[https://one.one.one.one/ Cloudflare WARP] is a further option after DNS changes. Setup is documented in Cloudflare's [https://developers.cloudflare.com/warp-client/get-started/ WARP client get-started] guide.
</div>
 
<div lang="en" dir="ltr" class="mw-content-ltr">

L'EDNS ECS fournis un hébergeur plus proche que les serveurs DNS traditionnels, ce qui peut être plus facile à utiliser sur des fournisseurs de services cloud qui hébergent en général dans le monde entier.  
<div lang="en" dir="ltr" class="mw-content-ltr">
Cloudflare documents two relevant modes:<ref name="cf-warp-modes">[https://developers.cloudflare.com/warp-client/warp-modes/ WARP modes] on ''developers.cloudflare.com''.</ref><ref name="cf-warp-vpn">[https://support.cloudflarewarp.com/hc/en-us/articles/360019372194-Is-the-1-1-1-1-app-a-VPN Is the 1.1.1.1 app a VPN?] on ''support.cloudflarewarp.com''.</ref>

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''WARP''' (tunnel) mode sends device traffic through Cloudflare. Cloudflare states that this replaces the original IP address with a Cloudflare IP that still represents an approximate location. WARP is not designed as an anonymizer or as a way to appear in a different country.<ref name="cf-warp-faq">[https://developers.cloudflare.com/warp-client/known-issues-and-faq/ Known issues and FAQ] on ''developers.cloudflare.com''.</ref><ref name="cf-warp-vpn" />
* '''DNS only''' mode sends DNS queries to Cloudflare and does not tunnel other traffic.<ref name="cf-warp-modes" />
</div>


=== Option 3 - Augmenter la priorité de l'IPv4 au dessus de l'IPv6 sur Windows ===
<div lang="en" dir="ltr" class="mw-content-ltr">
Cela accordera la priorité à l'utilisation de l'IPv4, sans pour autant désactiver l'IPv6.
VRChat Help notes that VPNs can slow downloads, and suggests disabling the VPN or excluding VRChat from the tunnel.<ref name="vrc-slow">{{VRC link|https://help.vrchat.com/hc/en-us/articles/14301364738707-I-m-experiencing-slow-download-speeds|I'm experiencing slow download speeds}} on ''help.vrchat.com''.</ref>
*Cette option peut ne pas fonctionner si votre FAI n'offre plus l'IPv4.
</div>


Pour activer sur Windows :
<div lang="en" dir="ltr" class="mw-content-ltr">
WARP tunnel mode can also break [[Special:MyLanguage/VRChat SDK|SDK]] uploads. [[Special:MyLanguage/Guides:Common SDK issues|Common SDK issues]] describes a "Missing Credentials" error while WARP is enabled, and recommends disabling WARP or switching to DNS-only 1.1.1.1 for that case.
</div>


* Ouvrir l'invite de commande en appuyant sur la touche « Windows », écrire « cmd », ce qui ouvre la console, puis appuyer sur « Éxecuter en tant qu'administrateur »
<div lang="en" dir="ltr" class="mw-content-ltr">
* Écrire « netsh interface ipv6 set prefixpolicy ::ffff:0:0/96 100 4 » et appuyer sur la touche « Entrée »
=== Disabling IPv6 ===
* Cela accordera la priorité à l'IPv6 après redémarrage de l'ordinateur.
Disabling IPv6 is a last option and is not recommended. Microsoft states that IPv6 is a mandatory part of current Windows versions, and that disabling or unbinding it can break Windows components.<ref name="ms-ipv6" /> On IPv6-only ISPs, disabling IPv6 can remove Internet access entirely.
</div>


Pour désactiver la priorité de l'IPv6 :
<div lang="en" dir="ltr" class="mw-content-ltr">
If IPv6 still needs to be limited on macOS, Apple documents a '''Link-local only''' TCP/IP option that limits IPv6 traffic to the local network.<ref name="apple-tcpip">[https://support.apple.com/guide/mac-help/change-tcpip-settings-on-mac-mh14129/mac Change TCP/IP settings on Mac] on ''support.apple.com''.</ref>
</div>


* Ouvrir l'invite de commande en appuyant sur la touche « Windows », écrire « cmd », ce qui ouvre la console, puis appuyer sur « Éxecuter en tant qu'administrateur »
<div lang="en" dir="ltr" class="mw-content-ltr">
* Écrire « netsh interface ipv6 reset » et appuyer sur la touche « Entrée ».
== Troubleshooting ==
* Cela devrait réinitialiser la priorité de l'IPv4 après redémarrage de l'ordinateur.
Connection problems can also come from a slow or unstable path, a local firewall, or the VRChat client itself. VRChat Help for Meta Quest, Pico, and Vive XR Elite includes restarting the headset, trying another network, power-cycling the router to renew the IP address, and disabling IPv6 firewall features on the router (this is not the same as disabling IPv6).<ref name="vrc-conn" />
</div>


===Option 4 - Désactiver l'IPv6 et forcer l'utilisation de l'IPv4 (NE PAS UTILISER)===
<div lang="en" dir="ltr" class="mw-content-ltr">
Plusieurs FAI commencent à retirer l'utilisation de l'IPv4 dû à une pénurie mondiale d'adresses IPv4.
=== Update VRChat ===
Si votre FAI se trouve dans cette situation, cette méthode peut ne pas fonctionner et risque de vous empêcher de vous connecter à internet.
Update the VRChat client if the store (for example Steam or Meta) shows an available update.
There are some available guides on how to disable IPv6 protocol if you knows what you are doing:

==Dépannage==
<div lang="en" dir="ltr" class="mw-content-ltr">
L'instabilité de la connexion peut être causée par des pertes de paquets ou du fait d'avoir une connexion internet lente ou instable. Il existe de nombreuses raisons qui explique une connexion instable. Voici cependant quelques méthodes afin de dépanner :
=== Reboot router ===
Power the router off, wait a few minutes, and power it back on. VRChat Help notes that this often renews the IP address.<ref name="vrc-conn" />
</div>


=== Mettre à jour VRChat ===
<div lang="en" dir="ltr" class="mw-content-ltr">
VRChat peut nécessiter une mise à jour! Un message peut vous inviter à mettre à jour votre client VRChat sur Steam ou le Meta Store.
=== Installation and drivers ===
Update GPU drivers and check the VRChat installation. Reinstall VRChat if needed.
</div>


=== Redémarer le routeur ===
<div lang="en" dir="ltr" class="mw-content-ltr">
Redémarrez votre routeur en l'éteignant, attendez quelques minutes, puis allumer le.
=== Firewall, antivirus, and ports ===
Make sure the firewall or antivirus is not blocking VRChat. VRChat Help suggests adding a firewall exception for VRChat, or temporarily disabling the firewall during testing, then turning it back on.<ref name="vrc-conn" /> Some users also add Easy Anti-Cheat to the same exception list.
</div>


=== Intégrité des fichiers ===
<div lang="en" dir="ltr" class="mw-content-ltr">
Vérifiez l'intégrité du microprogramme pour les drivers de votre GPU ou de l'application VRChat. Si nécessaire, vous devriez réinstaller VRChat.
VRChat Help lists outbound ports that need to be allowed on a strict firewall, including UDP 5055 and 5056 for realtime networking.<ref name="vrc-ports">{{VRC link|https://help.vrchat.com/hc/en-us/articles/360062658793-Which-ports-do-I-need-to-open-for-VRChat|Which ports do I need to open for VRChat?}} on ''help.vrchat.com''.</ref>
</div>


=== Autoriser VRChat sur votre antivirus ou pare-feu ===
<div lang="en" dir="ltr" class="mw-content-ltr">
Assurez-vous que votre pare-feu ou antivirus ne bloque pas la connexion à VRChat. Si nécessaire, VRChat et Easy Anti Cheat doivent être ajoutés aux applications autorisées de l'antivirus ou du pare-feu.
=== Output logs ===
On PC, VRChat output logs are under <code>%USERPROFILE%\AppData\LocalLow\VRChat\vrchat</code> and named <code>output_log_(date)</code>.<ref name="vrc-logs">{{VRC link|https://help.vrchat.com/hc/en-us/articles/9521522810899-Where-do-I-find-my-Output-Logs-and-Crash-Dumps|Where do I find my Output Logs and Crash Dumps?}} on ''help.vrchat.com''.</ref> For Quest, Linux, and crash dumps, see [[Special:MyLanguage/Guides:How to write efficient bug reports|How to write efficient bug reports]].

This guide covers connection issues with VRChat. Connecting to VRChat requires a reliable path to Cloudflare, AWS CloudFront, and Photon Engine.[1] Check VRChat's official status outlets before changing local network settings.

Glossary

This guide uses the following terms:

  • DNS — Domain Name System: a protocol that resolves a domain name to an IP address.
  • IP — Internet Protocol address: an address that identifies a device on a network.
  • ISP — Internet Service Provider: a company that provides Internet access. Examples include Comcast, Virgin, and NTT Docomo.
  • OS — Operating System.
  • Upstream provider — a third-party service that VRChat depends on for part of its infrastructure.
  • VPN — Virtual Private Network: software that routes traffic through another network, often changing the apparent IP address.

Check official outlets

VRChat publishes confirmed instabilities and outages through the following outlets.

On the web:

On Discord:

Help articles for connection, firewall, ports, uploads, and downloads are listed under #Official resources.

Upstream providers

VRChat depends on several upstream providers for account authorization, instance hosting, and purchases. Outages or maintenance on those services can affect sign-in, instances, and the Creator Economy. For Photon regions, Thunes, and related providers, see Server infrastructure.

Unstable connection

If the status outlets above do not show an incident, some users change DNS, prefer IPv4 over IPv6, or use Cloudflare WARP. This guide treats DNS as the first local change. Disabling IPv6 is not recommended on Windows, and it can remove Internet access on IPv6-only ISPs.[2]

Configure DNS

Write down the current DNS addresses before changing them, so the previous settings can be restored.[3] This section uses Cloudflare 1.1.1.1 as the example. Set 1.1.1.1 as the preferred IPv4 resolver and 1.0.0.1 as the alternate.[4] If the connection has IPv6, set that same provider's IPv6 DNS addresses as well. Do not mix one provider's IPv4 addresses with another provider's IPv6 addresses.

On IPv6-only networks, use the provider's IPv6 DNS addresses. Cloudflare and Google both publish IPv6 resolver addresses.[4][3]

Use first-party setup pages. VPN or security apps sometimes document their own resolver addresses; use those only if you mean to use that vendor's DNS. Otherwise use Cloudflare, Google, or another provider from the table below.

Cloudflare 1.1.1.1 addresses:[4]

1.1.1.1
1.0.0.1

Prefer IPv4 over IPv6 on Windows

Microsoft does not recommend disabling IPv6, unbinding IPv6 from interfaces, or disabling IPv6 components. Microsoft recommends preferring IPv4 over IPv6 in prefix policies instead, by setting the DisabledComponents registry value to decimal 32 (0x20).[2] This option may not work if the ISP no longer offers IPv4.

Microsoft warns that an incorrect registry change can cause serious problems. Back up the registry first, and restart the PC after the change.[2]

To prefer IPv4 on Windows:

  1. Open Command Prompt as administrator: press the Windows key, type cmd, then choose Run as administrator.
  2. Run:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v DisabledComponents /t REG_DWORD /d 32 /f
  1. Restart the PC.
  2. Optional check: run netsh interface ipv6 show prefixpolicies. The ::ffff:0:0/96 prefix should have a higher precedence than ::/0.[2]

To undo the change:

  1. Open Command Prompt as administrator again.
  2. Run:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v DisabledComponents /t REG_DWORD /d 0 /f
  1. Restart the PC.

Cloudflare WARP

Cloudflare WARP is a further option after DNS changes. Setup is documented in Cloudflare's WARP client get-started guide.

VRChat Help allows Cloudflare WARP as a last-resort VPN and states that some other VPNs may be blocked. Using a VPN may have legal limitations depending on local regulations.[5] VRChat Help also suggests trying Cloudflare WARP when content uploads hang because of ISP routing or throttling.[6]

Cloudflare documents two relevant modes:[7][8]

  • WARP (tunnel) mode sends device traffic through Cloudflare. Cloudflare states that this replaces the original IP address with a Cloudflare IP that still represents an approximate location. WARP is not designed as an anonymizer or as a way to appear in a different country.[9][8]
  • DNS only mode sends DNS queries to Cloudflare and does not tunnel other traffic.[7]

VRChat Help notes that VPNs can slow downloads, and suggests disabling the VPN or excluding VRChat from the tunnel.[10]

WARP tunnel mode can also break SDK uploads. Common SDK issues describes a "Missing Credentials" error while WARP is enabled, and recommends disabling WARP or switching to DNS-only 1.1.1.1 for that case.

Disabling IPv6

Disabling IPv6 is a last option and is not recommended. Microsoft states that IPv6 is a mandatory part of current Windows versions, and that disabling or unbinding it can break Windows components.[2] On IPv6-only ISPs, disabling IPv6 can remove Internet access entirely.

If IPv6 still needs to be limited on macOS, Apple documents a Link-local only TCP/IP option that limits IPv6 traffic to the local network.[11]

Troubleshooting

Connection problems can also come from a slow or unstable path, a local firewall, or the VRChat client itself. VRChat Help for Meta Quest, Pico, and Vive XR Elite includes restarting the headset, trying another network, power-cycling the router to renew the IP address, and disabling IPv6 firewall features on the router (this is not the same as disabling IPv6).[1]

Update VRChat

Update the VRChat client if the store (for example Steam or Meta) shows an available update.

Reboot router

Power the router off, wait a few minutes, and power it back on. VRChat Help notes that this often renews the IP address.[1]

Installation and drivers

Update GPU drivers and check the VRChat installation. Reinstall VRChat if needed.

Firewall, antivirus, and ports

Make sure the firewall or antivirus is not blocking VRChat. VRChat Help suggests adding a firewall exception for VRChat, or temporarily disabling the firewall during testing, then turning it back on.[1] Some users also add Easy Anti-Cheat to the same exception list.

VRChat Help lists outbound ports that need to be allowed on a strict firewall, including UDP 5055 and 5056 for realtime networking.[12]

Output logs

On PC, VRChat output logs are under %USERPROFILE%\AppData\LocalLow\VRChat\vrchat and named output_log_(date).[13] For Quest, Linux, and crash dumps, see How to write efficient bug reports.

VRChat User Support or the Discord support channel can help as a last resort.

System time

Check that the system clock matches the current time in the configured time zone.
