### Bug description
With NC28 I had no well-known URL errors, and no change to the NGINX configuration. After upgrading to NC29, I now have the following message:
`Your web server is not properly set up to resolve .well-known URLs, failed on: /.well-known/caldav For more details see the [documentation ↗](https://docs.nextcloud.com/server/29/go.php?to=admin-setup-well-known-URL).`
In the NGINX logs, I see a 401 errors:
```
192.168.9.6 - - [25/Apr/2024:13:02:21 +0000] "PROPFIND /.well-known/caldav HTTP/1.1" 301 162 "-" "Nextcloud Server Crawler"
192.168.9.6 - - [25/Apr/2024:13:02:21 +0000] "GET /remote.php/dav HTTP/1.1" 401 569 "-" "Nextcloud Server Crawler"
192.168.9.6 - - [25/Apr/2024:13:02:21 +0000] "GET /.well-known/caldav HTTP/1.1" 301 162 "-" "Nextcloud Server Crawler"

```
My Android DAVx5 client doesn't seem to have any issues and continues to work well.
A curl test, shows the 301 redirect working, followed by a 401, but I'm assume that's expected with an unauthenticated request
```
