I also stopped using Nextcloud after it broke a couple of times. As a consequence I also never use :latest tag on any docker container anymore - manual updates only

When I switched to Android phone, I also switched to syncthing. If you have enough storage on your phone, it is amazing! Never looked back

Thats frustrating

I second the notion that your ip was banned by nc's brute force detection

The silent reconnects of a DAVx client on a phone could easily trigger this

You can whitelist your home routers ip in the config IIRC Maybe not on the LISO container though, IIRC it is less configurable, but doesn't "just work", I'd ditch that not nextcloud

Quick fix could be to "DELETE FROM" (or "TRUNCATE" if you are certain nobody is blocked correctly) the table bruteforce_attempts (or smth similar). Although that "dc up && dc down" worked could indicate another issue, as you do seem to have persistence with your db in a docker volume (cred are still there) which would mean the time penalty ran out during restart or oits somethimg else

I just implemented authentik SSO for Nextcloud and other apps and it’s made my life easier.

If your main use case is photos

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 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
