Community:Connection Issues

Template:Noticebox/communityThere are currently multiple known issues regarding maintaining a stable connection to VRChat.

Unstable Connection (Limited IPv6 Support from ISP).

Option 1 - Using a VPN Tunnel.

If you're having connection issues it could be a good idea to try using a VPN Tunnel to stabilize your connection. To do so you'd need an app such as WARP by CloudFlare¹, which could be acquired here https://1.1.1.1/.

1. WARP by CloudFlare is a sort of VPN tunnel that aims to stabilize your connection, it also uses Cloudflares own DNS servers. It however does not hide your IP.

Option 2 - Configuring DNS Servers.

• Linux: https://support.surfshark.com/hc/en-us/articles/360021037760-How-to-configure-custom-DNS-on-a-Linux-device

The guides for DNS settings above will give you IPs to connect to the "SurfShark VPN" DNS servers, use the Cloudflare IPs instead.

1.1.1.1
1.0.0.1

1.1.1.1 (Server 1) should be your preferred address, while 1.0.0.1 (Server 2) should be your alternate address. However you can use any of these other DNS options if you would like.

You may choose any DNS provider, your options aren't limited to just Cloudflare.

EDNS ECS provide closer host as result than traditional DNS servers, it works better on Cloud Service Provider who do host worldwide mainly.

User Proof Check Failure/Connection Timeout

This can simply happen due to packets being sent out of order, or having a slow or unstable internet connection. Unfortunately there is no tried and true fix for these errors as they can be caused by many different issues however, here are some of the most common ones.

• System Time:

Double check your system clock against your current time with your timezone and make sure the time is set correctly.

• Unknown Connection Issue/Timeout:

Turn off your router/modem, wait few minutes and turn it back on once again. Sometimes just waiting a hour may also resolve your issues.

(If you turn back on too quick, your router may reset to factory default in some case)

• Slow File System:

Check the integrity of your drivers, and/or attempt to reinstall your OS.
