Hello everyone,
I’ve encountered a problem and don’t know what to do anymore. I’ve updated because of a miss configured automation to nextcloud 31 and needed to revert back to 30.0.6. I have the nextcloud docker container running on podman with persistent volumes. Every night I export the persistent volumes so I have a backup of all the data.
Now I’ve redeployed the container with the correct version and restored the persistent volumes to the date before the update to nextcloud 31. The container starts but on the web interface I receive the error: “Internal server error”.
The Basics
- Nextcloud Server version (e.g., 29.x.x):
30.0.6.2
- Operating system and version (e.g., Ubuntu 24.04):
Linux 5.14.0-503.23.1.el9_5.x86_64
- Web server and version (e.g, Apache 2.4.25):
Apache 2.4.62
- Reverse proxy and version _(e.g. nginx 1.27.2)
HAProxy
- PHP version (e.g, 8.3):
PHP 8.2.27
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
After importing old persistent volume data
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
Nextcloud docker on podman
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
Web server does not work after restoring persistent volume data.
Steps to replicate it (hint: details matter!):
- Stop the database container and the nextcloud application container.
- Import the old exported persistent volume data with podman volume import.
- Redeploy the container with the same version as the data on the persistent volume.

I’m completely clueless in regards to php or webservers in general.
Thank you in advance.
