The issue you are facing:
I’m running nextcloud in a docker with mariadb / letsencrypt / nginx-reverseproxy
After a backuprestore of my server, i cant upload anything.
Since the restore was only 1 day old an had no changes to the config or anything else i don’t know what could have caused this.
What did i try?
- filesystem check
- repair
- sync cache
- docker down + docker compose with same config
- update everything
Is this the first time you’ve seen this error? (Y):
Steps to replicate it:
- Upload file from anywhere (App/webinterface)
- Error
