Problem connecting to the server, only works locally

What behaviour is observed?

With AuthMe, I can only log in locally. If I do this while I'm connected to the server via my public ip, I can't log in.

I have investigated this problem, but no solution solved the problem. I don't host MYSQL

When I join locally it works very well 192.168.1.20 but I get this error in the console

then when I connect via my public ip, I can't log in even though I've entered the right password. 2024-04-26_12 05 37

and in the console
