Well, this happens when I try to join one game. It constantly says connection failed, but when I ask one of my friends to try logging in, they get into the server without any problem.

Game: Bleach Las Noches

I don't think I'm banned cause I eventually get into the server after several attempts.

This is the message I get:
Welcome BYOND! (4.0 Public Version 454.1036)
Logging in...connected
Logged in as Child Prodigy.
Connecting to byond://
Connection died.
Connection failed.

I tried reinstalling BYOND on my computer, restarting, and clearing the cache but nothing works.

Edit: All my keys have this problem and I'm not the only person experiencing this problem.
