Nextcloud multiple file download problem

ℹ️ Support
, , ,
1

Nextcloud version (eg, 20.0.5): 28.0.3
Operating system and version (eg, Ubuntu 20.04): DietPi v9.2.1
Apache or nginx version (eg, Apache 2.4.25): nginx version: nginx/1.22.1
PHP version (eg, 7.4): PHP 8.2.7

The issue you are facing:
When I want to download a file from my Nextcloud interface, a download file with the extension download.php.html appears and the error “the site could not be reached” appears. I can download files but when i try to download any folder download.php.html appears.

I have been using Nextcloud on my Raspi 4 with DietpiOS installed on it for a long time, but I can’t figure out what is causing this problem.

Is this the first time you’ve seen this error? (Y/N): Y
