7.16.1 - nfs bug?

Hi, updated to 7.16.1 and installed the rose-storage package. I’m trying to connect via NFS to my Synology, which supports the maximum version of NFS4.1 and it is enabled in the settings. My home Proxmox server connects successfully. But Mikrotik does not want to.

/disk add type=nfs nfs-address=192.168.230.3 nfs-share=/volume1/mt-nfs



# SLOT  MODEL                                INTERFA  RAID  NFS-STATE             
0 nfs1  nfs://192.168.230.3//volume1/mt-nfs  network  none  Protocol not supported

I started to take a dump, noticed that Mikrotik transmits the parameter minorversion:2 in the packet and the NFS server responds with the error Status:NFS4ERR_MINOR_VERS_MISMATCH.
After that, Mikrotik does not try to downgrade the version to 4.1.

Does this mean that only NFS4.2 is supported?
