Aternos Server Issues Prevent Friends from Joining—Requesting Fix

I set up an Aternos server, but my friends cannot join due to constant errors. These errors generate confusing and unhelpful codes, making it impossible for them to connect. This situation is incredibly frustrating and unacceptable for a platform that is supposed to provide an easy server experience.

I want to use this server with my friends, but these technical issues are making it impossible. Aternos, please address this problem and fix my server so that it functions properly. Reliable service is crucial, and I hope you can resolve this issue quickly. I need a working server without these unnecessary obstacles.
