Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can

Operating system and version (eg, Ubuntu 20.04): Debian 12.4

The issue you are facing:
- Your web server is not properly set up to resolve “/ocm-provider/”. This is most likely related to a web server configuration that was not updated to deliver this folder directly. Please compare your configuration against the shipped rewrite rules in “.htaccess” for Apache or the provided one in the documentation for Nginx at it’s documentation page
. On Nginx those are typically the lines starting with “location ~” that need an update.
Is this the first time you’ve seen this error? (Y):
Steps to replicate it:
- Install nextcloud.
- Change the nginx configuration file.
