Communication failure to storage in GUI

[Dzung]

Hey all,

When I look in the interface at the storage (any of the available storage options on this node), I get a "communication failure (0)" then change to time out (all local storage and nfs). VM's running on these storage arrays are fine, it's only a GUI thing.
See attachment.

How can I fix this? I've restart pve-cluster restart && service pvedaemon restart && service pvestatd restart && service pveproxy restart to no effect.
when run pvesm status all storage show active

when there is an error in the summary of vm is also broken, even though vm is still running
anyone tell me how to debug this

the problem comes from the proxmox backup server, after i reboot the backup server the storage is back in normally, i don't understand why all the storage has problems

Has anyone used proxmox backup server with the same error?
