Skyfactory 3 Server stopping as soon as it starts

When I start my Skyfactory 3 Server, it start regulary, and as soon as it gives the "Server Started"-notification , it says "stopping" and shuts down.

The world isn't corrupted and can be played in singleplayer without any errors, so the world isn't the problem.

Things I tried: Download and reupload the map. Reinstall the Skyfactory 3 software.

The Server worked yesterday.

Here is the NEW log-file (edited, because the Old Log seamed to have had an error) :

Thank you in advance.

I don't know why it's that short, that's just what it gave me when i pressed "share log" on aternos.

It happend again, and now I get a longer log, here it is:

Can you find any problems?

And where or how am I supposed to change the configs for that mod?

I don't see anything on the aternos page where I could edit the config.

Please tell me how/where.
