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.

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.

Option 3 - Elevate IPv4 priority over IPv6
This will prioritize using IPv4 over IPv6 without disable IPv6 completely.
To enable,
- Open command prompt by press "Windows Key" and type "cmd" then press "Run as Administrator".
- Type "netsh interface ipv6 set prefixpolicy ::ffff:0:0/96 100 4" and press "Enter Key"
- Restart your PC.
To disable,
- Open command prompt by press "Windows Key" and type "cmd" then press "Run as Administrator".
- Type "netsh interface ipv6 reset" and press "Enter Key"
- Restart your PC.
Option 4 - Disabling IPv6 and forcing IPv4 use. (NOT RECOMMENDED)
As some ISPs start removing IPv4 capability completely due to worldwide shortage of IPv4 address, if your ISP doing this, this method may not works and make you cannot connect to internet at all.

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.
- Firewall / Security Appliance:
- Make sure your PC/Security Appliance/Router/ISP side firewall not blocking connection to VRChat.
- You could use ping/nslookup/tracert from command line utility to find out.
- Output Log (Advanced):
- When you seek help from others or investigate further, it would be good idea to check output log file.
- It is located under "%USERNAME%\AppData\LocalLow\VRChat\vrchat" and named "output_log_(date).
- Check latest dated copy and find where issue happening.
- If you unsure how to read those logs, ask your friends or/and VRChat discord User Support Thread.
