Everytime I try to join a server, it says: Ended Connection: Unhandled error while syncing. I need help, this is getting me mad. I want to play with my friend.

I have the same error. I was running a server several weeks ordinarily, but now it gives out this error for anyone trying to connect my server.

Closting this - I'll need more info such as an output_log.txt. This was likely caused by using DMP 0.1.4.2 with KSP 0.24.
