Internal Server Error when trying to access the files

ℹ️ Support 📦 Appliances (Docker, Snappy, VM, NCP, AIO)

This might be a continuation of Nextcloud container doesn't start after restoring from backup. If not, the AIO label might be wrong.

When trying to access the files through the web interface, I see this:

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

There are no “technical details below”. This is the whole message.

Here are two tracebacks from the admin logs that should be relevant:

Happy to provide additional logs or information if needed.

Did you try to clear the opcache? There were several people who had problems with internal server errors which could be resolved by clearing that cache.

3

I have not. Could you tell me how to do it?

4

It also just seems to be an issue with the file view on the web server rather than with the storage in general. I can access my photos through the web interface. Plus, I can also access all files through the Nextcloud app on my phone.

Since I am using NextcloudPi it is

sudo bash -c 'source /usr/local/etc/library.sh && clear_opcache' 
sudo service php8.1-fpm restart

But I am not sure how to trigger it on a “normal” system.
