NFS logging on OpenSuSE 13.2?

I have a problem where my OSMC media center stops talking to NFS on OpenSuSE, the error I see on OSMC is:
‘open call failed with “NFS: ACCESS denied. Required access r–. Allowed access —”’

I tried to enable NFS logging, but the instructions were not very clear and I do not see a whole
lot of info from NFS in journalctl -r

Nov 29 19:28:53 tvburk rpc.mountd[29180]: authenticated mount request from for /home (/home)

I tried sysctl -w sunrpc.nfs_debug=1023

Do I need to restart NFS after that?
