NFS, access denied

I have an NFS server on a debian system. When I try to connect to this from volumio Beta1.3 I get the message:

Last system mount error
mount.nfs: access denied by server while mounting 

I was able resolve this by removing the


from the Mount flags in the advanced options.

ps: it would be great if 1.3 could be mentioned on the download page. Its hard to find out that it even exists without looking through the forums.

I still need to manually remove nfsvers in volumio 1.55

A quick google leads me to … tions.html
This states that the command is outdated since NFSv4 does not support it.
