Error cfs-lock 'storage-NAS

I have two Proxmox servers running currently. One is 8.03 and the other is 7.3-4 Eventually everything will be on the new server but I don't have all the vms moved yet.
I see my backups are failing with an error
trying to acquire cfs lock 'storage-NAS3' ...
trying to acquire cfs lock 'storage-NAS3' ...
trying to acquire cfs lock 'storage-NAS3' ...
TASK ERROR: cfs-lock 'storage-NAS3' error: got lock request timeout

And another one failing with error
TASK ERROR: 'storage-NAS3'-locked command timed out - aborting

These were both on the 8.0.3 version.

The version 7 server used to work fine but now it's also throwing errors

I even tried to manually go in and delete my backups but it won't let me do that either. I'm suddenly uncomfortable as I realize my backups aren't there. I see a lot of people seem to be having a similar problem but I don't see a solution in those threads. What do I need to do? Be specific as my Linux knowledge is limited and I'm sick on top of that so maybe not thinking as clearly as I'd like.
I rebooted the version 8 server yesterday. This morning it's not showing an error on either server (never touched the version 7 machine). It looks like all backups ran successfully last night. So I don't know what caused it, or what fixed it, but it's currently working.
