    Hello, this problem has been a headache for a while, as I read that it is a problem with mods, however, as far as I can see, no mod is different from the one on the servers, adding that my mods folder was shared towards a few friends, and they can get in, but I can't. What could I do?

    If you're 100% sure that they match exactly then you can try deleting your config folder on your pc and server.
