Can’t mount NFS share for Instant VM Recovery

[SerSunal]

I have a vCenter with four hosts. Running an Instant VM Recovery succeeds in mounting the NFS datastore on only two hosts. In the other two it indicates the error Can't mount NFS share. I have done a ping from the Veeam Server to the Esxi vmkernel port and vice versa and in both cases there is connectivity.
What could be the reason why the NFS datastore for IR can be mounted on two hosts and the others cannot?

Hi.

We have a KB1284 with manual NFS mount testing procedure. Do check related links at the bottom of the article for more relevant info.
And as anytime facing a technical issue, remember that you can request a support ticket to investigate the case with our support team.

/Thanks!

Currently the Veeam datastore is mounted on two hosts. If I want to add it manually to the other two hosts, it gives an error. Same error when Running from Veeam the IR to one of those two hosts.
