Well, I'm amazed you didn't get downvoted to hell by saying NC is bad. Some of my experiences with NC are described in detail at https://lemmy.world/comment/1571886 and https://lemmy.world/comment/346174

Do you have 2 redis containers by any chance? I'm asking because you mentioned Immich, and that one has redis as part of its stack
I just implemented authentik SSO for Nextcloud and other apps and it’s made my life easier.
I would like to recommend Seafile if immich doesn't work out. I've used it for a long time and it's always been the best self hosted cloud imo. it's not as shiny or pretty looking as some but it's been reliable
Are you exposing it to the Internet? Weirdness like that might be from someone exploiting your instance.
Yeah - don't see any evidence of that in the logs + why would it work again after a restart?
How do you have your auth working? Is it basic user/password managed on Nextcloud (external database connected?), is it external auth against something like Okta, or is it user/pass that you define from docker-compose?
If via docker-compose then a restart would clear anything an attacker would have done and it would reload from the docker-compose process I think? I’m not too familiar with the specifics on that as I’m not a security researcher, but generally some attacks are resident in memory only and a restart can clear them only for it to crop up again later either due to a running process that was set to rerun an exploit or someone monitoring your system externally and retrying the exploit remotely again.
Or it could just be some bug in Nextcloud or unique to your environment. Personally I’m only hosting things that are internally accessible via VPN anymore. Tailscale makes that super easy these days.
