Hello, I am getting this error when connecting to a new forge world I'm working on. All of the mods match and the server boots perfectly fine. The server log just shows the reason for disconnect as "Disconnected". I've logged out and logged back in, ensure compatibility of all mods, set the server settings to default, restarted it probably a dozen times. Apart from removing each mod to see if one of them is causing this, is there anything else I should try first?
The specific error is basically impossible to Google because of it's length.
Failed to connect to the server
