anything nfs changed recently?

I have couple rpi3 LibreELEC (official): 12.0.0 (RPi2.arm) running kodi served from rockpro64 Slackware-current AArch64 all up to date.

nfs shares connected fine last week now they're not.

so as subject says "anything nfs changed recently?"

or if not what can I do to diagnose?

Thanks
