NFS not working after upgrade to omv6

Hello All,

I recently noticed that NFS wasn't working anymore on my omv server, I think it happend after upgrade to OMV 6, didn't notice any errors after update but when I tried to add a nfs-share on webinterface, I couldn't apply changes , keeps giving big error messages.

when I try to start nfs-server from cl, I get depency error;

root@jacksbox3:~# systemctl start nfs-server.service

A dependency job for nfs-server.service failed. See 'journalctl -xe' for details.

Please go to the NFS settings page and re-configure the service.

Select the required NFS versions and uncheck the Enabled checkbox. Save. Enable the checkbox again. Save. Apply the configuration.

ctrl-shift-R?

I did search the omv and debian 11 forums and read throw very many topic related to nfs-server not starting but did't find a fix for my situation , so thats why I started a new thread here.

Please clear your browser cache. The browser is not showing the latest page which contains a dropbox to choose the NFS versions.

Thanks Votdev, that did the trick, NFS working fine now.

SOLVED.
