[20:53:30] [main/INFO]: [STDERR]: Caused by: java.lang.RuntimeException: Failed to load AE2 config: C:\Users\eczaj\AppData\Roaming.minecraft\config\appliedenergistics2\client.json

just move that file somewhere else and restart the server as far as i am aware it should regenerate itself .... also post a copy of that file or compare it yourself with the generated one, to see if you can spot the difference

just as a hint: the logfiles mostly contain stuff you may not untderstand but the essential informations are most the times easy to find by just a little bit searching ... and tey are mostly somewhere inside the large "Exception" or "stacktrace" blocks

just like this one i quoted at the top of this comment

Thank you for the help, I’m close this issue tomorrow if it works!

you have a broken config, backup your config and generate a new, then check if it still fails

How can I do that?

It worked! Thank you!
