Can't mount NFS drive, permissions denied

[hepp3n]

Hello!

I'm not sure the issue here. When i'm trying to mount my NFS drive which is discovered just OK, I got dialog with permission issue. It says in logs:

[2025-01-22T19:37:29Z WARN  cosmic_files::tab] failed to scan "nfs://openmedia.local:2049/export/DATA": Podane położenie nie jest zamontowane
[2025-01-22T19:37:29Z WARN  cosmic_files::app] failed to connect to "nfs://openmedia.local:2049/export/DATA": Brak uprawnień: być może ten komputer jest niedozwolony lub wymagany jest uprawniony port

first line: Location is not mounted.
the second line: No permission, maybe this PC is not allowed or required is allowed port.

I'm kind of noob in this topic. Just setup my NFS on OpenMediaVault followed some tutorials 😅
When I'm mounting it from cli with sudo it works. Should not be there any polkit dialog to elevate permissions? Maybe it's missing.

Any advice what's needed to mount this drive in cosmic-files? Thanks :)
