Cannot mount with NFS on a Windows Server 2016

Hi everyone!
I am trying to mount a folder shared on an Ubuntu 22.04 from a Windows Server 2016 ‘client’.
I can mount the folder from other linux machines.
All machines are in the same tailscale network. They show together in my console.
At first I couldn’t even ping the linux machine. I oppened ports 41641/udp and 3478/udp as suggested in nd now I can at least ping.
But I am still receiving a Network Error - 53.
Did anyone face the same issue before?
Thank you,
