errors with forge

i'm trying to make a server for me and my friends, but it crashes every time i try to start it
the server is

taderz.aternos.me

my ingame user name is tadeez

here's the log: https://mclo.gs/8JnHF5d

i have no idea what's wrong, or how to fix, so i'm asking for help

i've tried to turn on the server, same result as before

very sure that is the full log, wont show me anything else
link to log again: https://mclo.gs/eKLnBZo

i've also included a screenshot this time

nevermind, it works now (?)

i've tried to turn it on again, and now it turns on, no idea what happened, sorry for wasting your time
