try joining on a version that isn't 1.19+
1.12 is recommended
It did nothing, although the message is different:
"Failed to login: Invalid Session (try restarting your game) - even if I restart the game a few times, it doesn't do anything. Really, nothing like this has happened before. Maybe it's a bug because by entering other servers everything works, only on this server something is wrong.
Here is photo evidence, maybe I'll make a video later (if needed).
Proof:
Version 1.12 (recommended)
Here is the version I've always played (as of Wednesday 10/06/2023) and never had any problems:
This mod didn't affect the game in any particular way either. It's just a visual mod, I've played on it too.
As you can see, the error is the same. It doesn't work, no matter how many times I try. I do not know what to do. I can't fix it myself because I don't know what the problem is.
