Error by reloading the Files App

Hello everybody,
I have a problem with the “Files” app on my NextCloud instance.

Too the information of the instance / server:

KVM root server, standing in a data center
KVM root server - 4 cores, 8 GB RAM, 50 GB SSD
- Processor: Intel Xeon E3-12xx V2 (Ivy Bridge) (4 CORES)
Debian 11
- Linux 5.10.0-13-AMD64 X86_64
NextCloud Version: NextCloud Hub II (23.0.3)
PHP version: 7.4.26
- Work memory limit: 1 GB
- Maximum execution time: 3600
- Maximum size for uploading: 2 GB
Mariadb server (Docker container)
NextCloud instance provided by a docker container
Network: Bridge (eth0)
Instance was created before about one week

To define:
When I go to my cloud in the Files app, the path changes
That’s not really the problem.

The real problem is when I then [...]/apps/files/?dir=/&fileid=6 new reloading. I have no access to the file structure. (See image)

Only when I [...]/apps/files/ I will be forwarded to [...]/apps/files/?dir=/&fileid=6 and then see my files again. Can I fix this somehow? I hope you could help me here. For questions please simply write under this thread.

Kind regards


just missing a bit of information in your config, apache2 or nginx ?

If nginx, it look like a reverse-proxy error
If apache2, might be a .htaccess error, a php-fpm error…

Okay i was in the Container Terminal. And i can found thats nginx. But how can i fix that?
