Describe the problem

I'm unable to connect to my netbird network.

To Reproduce

I try to connect to the network like so:

netbird up

Expected behavior

It should connect, but all it does is hang forever.
When I finally Ctrl-C out of the command, I get the message:

Error: unable to get daemon status: rpc error: code = Unknown desc = create wg interface: error creating tun device: no such device

There are no logs in /var/log/netbird/

Are you using NetBird Cloud?

No, it is self hosted.
I have many other peers that are able to connect perfectly, even with the same client version (0.36.5)

NetBird version

0.36.5

NetBird status -dA output:

netbird status -dA
Error: status failed: create wg interface: error creating tun device: no such device

Do you face any (non-mobile) client issues?

Please provide the file created by netbird debug for 1m -AS.

A reboot fixed the problem, though I now have to login again, after which it created a totally new peer :/
