This is a problem that has been happening to me since I started playing VRCHAT on Oculus quest 2 via SteamVR, thanks to this it is one of the reasons why I can’t comfortably play a game for which I bought my Oculus.
Entering the game and logging in everything goes great until after a while when trying to change Skin nothing happens and it doesn’t let me enter other worlds either, the only way I find is to close the game and open it again which hinders the gaming experience having to repeat: Enter the game, Log in entering name and password, And the error appears again which happens every few minutes, And the cycle repeats itself over and over again.
I have tried reinstalling the game multiple times and even formatting the virtual reality glasses themselves.
Try playing VRChat in desktop mode on that PC.
That sounds like VRChat doesn’t get along with your internet service provider (isp)
Personally I’m curious what would happen if you log in via steam instead of a VRChat account, would things be the same, or different?
Personally I linked my steam account so that if I log in via steam, I actually log in as myself rather than like “Docteh b15f”, but that’s not for everyone.
