Hello,
me and some friends got a server on verygames and started to build a server, but when we started it, i couldn't connect while all my friends with exactly same version and same files can play without problems
When i try to log in, after 10-15sec i got disconnected and got the following message : Internal exception: java.io.IOException: Une connexion existante a du etre fermée par l'hote distant
I posted a capture of the message in the console.
my version of forge is 1.15.2-31.1.41 and minecraft version is 1.15.2
