This is a bug that originated during the beta phase—which introduced the current nameplate and UI designs—and it has persisted into the public/live version. It is also currently present in the BETA and UNITY-6 versions.
The error occurs following packet loss, a lag spike, or a momentary disconnection. VRChat then displays one of the following messages:
-VRChat is not responding
-VRChat is time out
-VRChat is disconnected
However, upon attempting to reconnect, the application gets stuck on an infinite "Connecting" screen and remains that way until VRChat is completely restarted.
Through testing, I noticed that this error occurs when wearing a "Very Poor" avatar. It does not happen when using avatars rated "Excellent" through "Poor."
Here is what I have ALREADY TRIED to fix it:
-Completely uninstalling and reinstalling VRChat like new
-Uninstalling SteamVR
-Clearing the entire VRChat cache
-Updating network adapter drivers
-Clearing the DNS cache
-Factory resetting my modem/ONT (provided by my ISP) Internet speed 500 Mbps
  • Nothing in BETA version.
The error persists when wearing a "Very Poor" avatar. Consequently, I recorded a video demonstrating how to reproduce the issue, which I have attached to this post.

In the video, I used two avatars: one "Excellent" and one "Very Poor." I simulated an internet disconnection by simply unplugging my LAN cable for 15–20 seconds to trigger the "time out" message. I am also attaching the output_log files from each session shown in the video:
  • Avatar_Excellent_output_log_2026-08-14_01-03-37 – For the optimized avatar.
  • Avatar_VeryPoor_output_log_2026-08-14_01-23-05 – For the "Very Poor" avatar, where the error/bug preventing reconnection occurs.
I would also like to highlight the following lines from the log file where the error occurs:
1.- Error - [NetworkTransport] Failed to raise deferred operation of type 13.
2.- Error - SocketWebTcp.CloseCallback(). Going to disconnect. Server: wss://ns.photonengine.io:443/ Error: 1005 Reason:
3.- System.Exception: Failed to raise deferred operation of type 13.

These lines appear repeatedly when the error occurs, indicating that the session will not reconnect.
I hope you can help resolve this error, as it is very frustrating to have to completely restart VRChat whenever this momentary disconnection happens.
