Server Crashing and Internal Server Error

Hi Aternos Team, I've been creating a server on Forge 1.15.2 and the server crashes or gives internal server joining when trying to join.

Here's the log: https://mclo.gs/Vtu9XyX

I don't know what do I tried to reinstall, no player data and I can't even get in. Please resolve this issue. Thank you Aternos Team

Now this error https://mclo.gs/WH1UB5i

In another server with the same mods and configured, this errors happen https://mclo.gs/8lZcW8a

Yep so I finally found the problem iit was Security Craft. So maybe an older version could resolve that?

Well nothing works...

I don't know what to do

Roman, I find the problem finally. It was the Druidcraft mod. Now it works
