Caldav and carddav setup


I’m getting an error message on a plesk server, that caldav and carddav setup are not correct.
The documentation says, that I should redirect e.g. ./well-known/caldav to …domain/remote.php/dav
I found a file remote.php, but create a subfolder of a file??? Should I create a remote.php directory and then a folder dav?

Thanks in advance
