[SOLVED] Need help: Storage/CT/VM Status unknown

[danieljai]

Background​

• A Docker CT got stuck, wouldn’t shut down, so I killed the process.
• After that, the CT wouldn’t start. Tried all options, no success.
• Decided to restore a periodic backup from my NAS (Unraid).
• Restore process started but froze—no progress %.
• Restarted the node, then physically rebooted the machine.
• all CTs, VMs, and storage show Unknown status. GUI become unresponsive. [fixed]
• removed unraid_connection, restarted, All status back to normal

Issue
I cannot re-add the network storage through Datacenter > storage. Connection error - Timeout.

Need some help, as I'm out of ideas. Trying to solve this for hours. I'm not sure what else I can do...

Solved
...for now. Restarted unraid and I was able to add the connection back. Trying to restore the backup, hasn't shown even 1% yet. Hopefully it works.
