Nextcloud version: 26.0.5
Operating system and version: UNRAID 6.12.6
Apache or nginx version: nginx/1.23.3
PHP version: PHP 8.2.7
The issue you are facing:
I can no longer access my personal Nextcloud. I use UNRAID. My UNRAID USB boot device failed so I created a new one. Everything was working except I could not update the dockers for Nextcloud, mariadb, and swag on the UNRAID server. Online forums seemed to indicate that I could delete the dockers and reinstall them and point the Nextcloud docker back to the folder, everything would work correctly. Saddly, this did not work. I probably misunderstood what they meant… My files are all still on the server (I can see them on the drive in UNRAID) but Nextcloud is not accessible in a web browser do to a 404 Not Found nginx error.
I’m guessing there is some setting maybe in the Nextcloud config file or setting of mariadb that I need to fix…
I tried to follow this video tutorial to re-setup my Nextcloud but I can’t follow it once it gets to 7:48 https://youtu.be/id4GcVZ5qBA?si=Hg8zmS7r9BU0PC3P
Obviously, I reused my Nextcloud data folder instead of creating a new one…
I’m also getting errors like this in the docker log:
Next Doctrine\DBAL\Exception\TableNotFoundException: An exception occurred while executing a query: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'nextcloud.oc_appconfig' doesn't exist in /config/www/nextcloud/3rdparty/doctrine/dbal/src/Driver/API/MySQL/ExceptionConverter.php:51
Any help is greatly appreciated. I messed this up pretty bad I think. 
Is this the first time you’ve seen this error?: Yes
Steps to replicate it:
- Install Nextcloud.
- UNRAID USB drive failure
- Create a new USB drive
- Nextcloud still works but docker won’t update
- Try to remove Nextcloud docker, mariadb docker, and swag docker (dumb!!)
- Reinstall mariadb docker and Nextcloud docker pointing it back to Nextcloud data folder
- Nextcloud starts but with some errors and cannot access Nextcloud in a browser using local address. Get 404 Not Found nginx error.

I don’t see a nextcloud.log file… Maybe I’m looking in the wrong spot…
