Same issued… had to revert back to 6.6… The support on their Discord keeps saying “wrong setup”, instead just passing you an tutorial video and not taken the time to help out. Funny how reverting back to 6.6 fix everything. Even tried a fresh install on another server, and on a brand new VPS but it keeps happening.

Kinda sad “support”

I’m also having this problem, who has the solution?
