OMV is reachable by netbios name but not by IP

Hi! I have RPI4 wit OMV 5. I am facing a strange situation. It is possible to ping OMV, it is possible to access SMB shares via netbios name. But it is not possible to access the share via ip address. I have experienced opposite issues due to DNS settings before, but not like this one.

Client - WIndows 10 PC
It is possible to connect to SMB shares by ip address from ios devices (i have not tried others)/

I remember not being able to access OMV 4 SMB shares after on of the windows updates due to SMB versions on OMV.

What might be the possible cause?
