### Steps to reproduce

1. I set up the 4 well-known uri's as described here: https://docs.nextcloud.com/server/latest/admin_manual/issues/general_troubleshooting.html#service-discovery-label
2. kde's kontact works to login with login to https://domain.tld
3. nextclouds client at least for android expects to add the subdirectory to the login, while 3rd party apps work with service discovery

### Expected behaviour

i expect nextcloud to follow same service discovery as 3rd party apps do.
Thatfor i would expect its a bug and just doesnt work while its supposed to

### Actual behaviour

nextclouds android client (maybe all clients?) just fire the request to the domain for the /status.php uri and expect it to work. you'd need to add the subdirectory.
