Caught exception from Minecraft Forge (forge)

[lolus123]

Hello, I've a problem with connecting to my friend's server with mods. The server kicked me and I couldn't rejoin to server anymore. It was all fine before the error that is shown on the picture below. Im asking you guys for help with my problem. The game is set on 1.12.2 with latest forge version for 1.12.2. Like I said, the game was totally fine and the game just kicked me out of the server.
