I've been reading nextcloud forums/reddit/lemmy/etc. for years now, and i feel like 90% of the problems are from people using docker or whatever easy one-click solution is out there
I've been running NC the old fashioned way for years now and i've never had problems of NC dying for no reason.
Have i had issues? Of course.... Not not like the ones people keep coming here and shitting on NC
The only times i've had major issues and it was actually a problem with nextcloud, is buggy major version releases... So i never install a new major release until X.0.1 these days. Havent really had problems since
