No connection NFS on Synology

[netsaver]

I am running a synology NAS on 192.168.0.100 with NFS activated.
Share "proxmox" has been set on synology with user rights R/W.
It is visible to * with NFSv4.1 active. (I have tried 3.0 before, same results)

The NFS Share can be found and accessed from local Mac computers.

Any help is appreciated.

nmap from within Proxmox PVE host can ping synology and will find that NFS service is active on synology:

Hi,

I would re-check the NFS configuration on the Synology NAS. And ensure that the export settings are correctly configured and that your Proxmox Node's IP address is either explicitly allowed or not restricted.
