No one can join my server! Please help!

[Alaska]

According to my console, no one can join my server! Every time someone tries to join my server, my console just responds with an "Authentication Failed for [Xname]." Does anyone know how to fix this? I have port forwarded already, so that cannot be the problem.

Also, I have a strange feeling that RTB has to do with this...

Have you tried uninstalling Blockland? If you have and it didnt work, try to reset your modem or may even have to replace it. RTB has nothing to do with it. Or are you just having it on LAN so noone can join?
