Many 401 and some 405 errors in Nginx Proxy Manager logs with DAV services in nextcloud-aio Docker container

Nextcloud version (eg, 20.0.5): Nextcloud Hub 7 (28.0.3) (nextcloud-aio docker)
Operating system and version (eg, Ubuntu 20.04): openmediavault 7 / Debian stable

The issue you are facing:
I’m running nextcloud-aio on openmediavault 7 behind Nginx Proxy Manager (in docker, jc21/nginx-proxy-manager:latest, configured as described here). Everything is working fine, I have Ubuntu Desktop, Windows and my iPhone set up and syncing with nextcloud, including GNOME Calendar, GNOME Contacts, Evolution Calendar and Contacts and iOS Calendar and Contacts. All of this is synced without problems.

However: I have fail2ban set up to scan my npm logs and react to any 401, 403, 404 and 405 errors. Somehow, I get several 401 and occasional 405 errors from iOS, Evolution and Gnome contacting DAV services.
For now I had to remove the 401 filter from fail2ban in order to not get banned all the time.
The syncing itself seems to work well. Also I see the real IP and not internal or Docker IPs in both the npm and the nextcloud logs.

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

Steps to replicate it:

  1. Set up nextcloud-aio with Nging Proxy Manager in Docker
  2. Connect iOS or GNOME Online Accounts or Evolution to sync Calendar and Contacts
  3. Check the NPM proxy-host-1_access.log.

Is there a way to get rid of these 401 and 405 errors?

Adding things like this to the npm advanced config didn’t change anything:

    location = /.well-known/carddav {
      return 301 $scheme://$host:$server_port/remote.php/dav;
    }
    location = /.well-known/caldav {
      return 301 $scheme://$host:$server_port/remote.php/dav;
    }

I also tried this under advanced configuration for npm:

    location ^~ /.well-known {
        # The rules in this block are an adaptation of the rules
        # in `.htaccess` that concern `/.well-known`.

        location = /.well-known/carddav { return 301 /remote.php/dav/; }
        location = /.well-known/caldav  { return 301 /remote.php/dav/; }

        location /.well-known/acme-challenge    { try_files $uri $uri/ =404; }
        location /.well-known/pki-validation    { try_files $uri $uri/ =404; }

        # Let Nextcloud's API for `/.well-known` URIs handle all other
        # requests by passing them to the front-end controller.
        return 301 /index.php$request_uri;

        location /.well-known/nodeinfo {
                default_type application/json;
                return 404 '{"message": "nodeinfo not supported"}';
                add_header x-nextcloud-well-known 1 always;
        }

        location /.well-known/webfinger {
                default_type application/json;
                return 404 '{"message": "webfinger not supported"}';
                add_header x-nextcloud-well-known 1 always;
        }
    }

client_body_buffer_size 512k;
proxy_read_timeout 86400s;
client_max_body_size 0;

and all the trouble shooting for .well-known-redirections outlined here turned out fine.

I still got the 401 errors after that when accessing my calendar from iOS.
