the connection fails before choosing teams

[gatomafia782 0]

everything on the servers works till i get to choose teams, the screen goes black and it shows a message saying something along the lines of "The connection with the other players failed" and it returns me to the lobby automatically, i tried disabling the auto port thing in settings and writing the default one, the hosts file works fine because it wouldnt let me even enter the servers otherwise, and it isnt a proximity issue since i tried this with a friend that lives like 5 blocks away lol

thank you

I think you have virtual ip because of your internet providers ipv4 problem. To fix this problem you must talk with your internet provider and maybe you need buy static ip to fix this problem completely.
