Hi,

I turned off my server for a few hours and then turned it back on.

Since I turned my server back on, I've had this alert:

I tried to recover the key, but I got this error:

I have a valid key, I recently upgraded from Basic to Plus a few days ago and I had upgraded my key.

I've looked at the flash drive on my PC and I've got the /config folder with the key files in it.

What can I do?

I've tried to restore my key using Unraid USB Creator and the backup file generated in Unraid Connect but I don't see a /config folder in it and I haven't dared restart my server because at the moment there's the Home Assistant VM and several Docker containers running and I don't want to take the risk of them not restarting...

Copy the key file manually to the flash drive config folder and reboot, if you still get an error, post the diagnostics.

@JorgeB OK, I put the key on the drive, put it back on the server, restarted the server about ten minutes ago, but no access to the web interface...

You can get them from the CLI, see the link

@JorgeB Ok, I've come a long way...

The server wasn't booting with the backup file installed via Unraid USB Creator, so I didn't have access to the CLI either.

In fact, when I explored the drive on my PC, a lot of things were missing (for example, there was only one folder)...

I tried several times, same problem.

So I created a new key via Unraid USB Creator by putting the key file in it but I had the fright of my life when I started up and saw on the web interface that there was nothing left: no disk, no application, no VM, nothing.

I plugged the drive back into my PC and tried something else: I opened the backup zip (which does contain all the folders), copied/pasted it onto my key, overwriting the files created by Unraid USB Creator, put it back into the server and... it works! I've got everything back and no more key errors.

Could there be a problem with Unraid USB Creator?

Thanks for your help.

Maybe, if you can, try restoring that zip to another flash drive, and then check the folders.

@JorgeB I have just tried to restore the same ZIP to another flash drive and same problem here, as you can see on my screenshot (at left the new flash drive, at right the content of the backup ZIP file):

/config and /EFI are missing, and those folders are not empty on the backup ZIP file.

Unraid USB Creator told me that the restoration was complete.

My key is 4GB, the backup is only 719MB. The other key is 256GB. So free space isn't the problem here.

Please send that backup zip to me in a DM, if it's too large to attach, you can upload it to a free hosting site, like wesendit, then please send me the link.
