Problem Description


The alert I recived: The Minecraft server repeatedly failed to start, this is not a fault with AMP - you should check your Minecraft servers log files to find out why it is unable to start.

I am not very tech-y and am lost as to how to fix it.

Here’s a part of the log for the crash

Description: Exception in server tick loop

java.lang.IllegalStateException: Failed to initialize server
at net.minecraft.server.MinecraftServer.method_29741(
at net.minecraft.server.MinecraftServer.method_29739(
at java.base/

Reproduction Steps

  • I opened the game panel to find the server wasn’t running.
  • I clicked manage and clicked start.
  • It was unable to start with an alert letting me know it was not a fault on the AMP’s end and to check the files.

Is this a new server or an already existing server?
Would you mind tossing the log over with

Existing server, and I’ve never used that before so I hope this is what you were asking for!

Please let me know if there’s anything else I can send or if that wasn’t the right log.

The logs/latest.log sometimes has some extra info, would you mind shooting that over?

Of course, thank you:

Ah, that’s it. Stop/start-ing the instance from the main panel should clear up the port issue, then I’d suggest either disabling sleep mode or removing any scheduled restarts you may have in the scheduler. There’s a bug atm where if both are triggered at the same time it’ll lock up the port

This fixed it, thank you so much! I wouldn’t have gotten up again without your help

No worries! This is just one of the weird quirks that shows up every once and awhile
