Nextcloud down after update Cloudron 8.3.0

[thibault]

Hello everyone, last night my Cloudron server was updated to version 8.3.0.
However, I had quite a few applications with errors due to Postgres. After restarting the applications, everything went back to normal, except for some where the installation was as if it had no data. Luckily, I had the backups.
However, for Nextcloud, even when trying to update ("Application Information
Application Name and Version: Nextcloud 31.0.1
Application ID: 64663b1b-b940-4eaa-9ae7-47b2a722f676
Package Version: com.nextcloud.cloudronapp@5.3.1
Installed: 06/16/2024
Last Update: 5:25 PM"), the application remains stuck and unresponsive, and when I look at the logs, it seems like it's looping.
Here is part of the logs:

2025-03-14T17:37:47+01:00 An unhandled exception has been thrown:

2025-03-14T17:37:47+01:00 PDOException: SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "oc_appconfig" does not exist

I restarted the server, but it doesn't work.
When I try to access the NextCloud application console, I get the message "connecting and reconnecting" in a loop.
I also tried increasing the RAM size to 9GB, but nothing works.

Can you help me ? thanks a lot

@thibault for nextcloud, can you go to Services -> Postgres -> Give it a lot of memory. Then, restore Nextcloud . Can you try this?

@joseph I put 3 GiB in Postgres, I restart the server, but I still have this message: March 14, 20:24:18 Next OC\DB\Exceptions\DbalException: An exception occurred while executing a query: SQLSTATE[42P01]: Undefined table: 7 ERROR: The relation "oc_appconfig" does not exist. And the startup remains in a loop...

@thibault after you gave the memory, you have to initiate a restore from the latest backup. Not clear from your message, if you did that.
