A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Just had NextCloud denying my credentials (not for the first time). I know they weren't wrong because I'm using a password manager. Logs didn't say much. Was about to reinstall (again, not the first time nextcloud went bonkers on me) before I tried a docker compose down && docker compose up. Lo and behold after a restart the credentials worked again.

This stuff is just way too flaky for something so important.

Is OwnCloud good again? My main usecase is saving photos but I don't want them locked away in a database so SeaFile is out.

Edit: I'm going to take the time to reply to you all, bit busy with work and family suddenly. But a little update - I've quickly setup Immich and fired up the CLI to import my library. AFAIK the files are still stored on disk somewhere but metadata is in a database. I didn't realize this before, knowing that I think my mind is made up and Immich is the best solution. Thanks everyone!

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.
