Disconnect on Sync

[KoshiirRa]

Sevtech user here. A lot of us on the server I'm playing on are getting disconnected with the error "java.io.IOException: An existing connection was forcibly closed by the remote host" when advances try to sync on login. We're unable to use the /tf leave command as well to try and get the game to stop syncing advancements since it appears that nothing we type in chat goes through in the time between the mod reporting that it will sync soon and when it tries to sync.

Sorry about that, here's a client log from AT Launcher. I can get the server logs, I just have to wait for the server admin to show up again.

I'm also starting to think this isn't being caused by Together Forever. I managed to stay in long enough to drop my team by spamming the command, and it still kicks me out after ~30 seconds. Gonna close this issue, sorry about this.

Reviving an old thread - but did you ever find a resolution? @KoshiirRa

We're having the same issue with 3 players - and on of the players consistently disconnects right when it says syncing team data.
