However, with pktt trace shows that NFS server throwing "NFS4ERR_DENIED" error. I do not see any errors on the NetApp logs. Please note, the export policy and export-policy check does show that the client has RW access.

NFS3 works well with UDP protocol but not with NFS4. Suddenly the mount points doesn't show up with "df -h" command and this only happens after reboot of the Linux server.

The NFS4 exports works well until the server actually rebooted.

All went well, until we started seeing our RHEL 7.7 machines encountering NFS4 mount issues after reboot. I recently upgrade our FAS 2240-4 system ( EOSL) from ONTAP 8.3.2P12 version to 9.1P20.
