ZeroTier readd after deleting LM does't work

[gdimaria]

Hello, after restoring a backup disappeared the connection to ZeroTier, meaning that in the console there was but it was always offline.

Then I deleted it from the zerotier console and immediately readded through its id-node, but now it is still offline and I can not assign a new zerotier IP.
on LM the zerotier service is in "requesting ip address" state andi doesn't always stay that way whatever it does.

 I also reinstalled the firmware to the latest version, no way.

What I can do?

Thanks

Peppe
