[Bug]: Incompatible FML Modded Server

[TheJimmyJob]

Possible Fixes

Yes

Modpack Version

1.1.2

What happened?

I am currently playing an ATM9 To The Sky server with a friend. While placing framed vertical half slabs I suddenly could no longer interact with the world. Upon attempting to relog I was greeted with Incompatible FML Modded Server. We are running identical versions of Forge (47.2.20), Minecraft (1.20.1), and ATM9 (1.1.2). We have the same amount of mods installed. I have tried repairing the pack through CurseForge, reinstalling, downgrading, and installing it through AT Launcher

Try putting the port in with the IP on the server list it should be like this:
IP_Here:PORT_Here
