Original GitHub issue: https://github.com/netbirdio/netbird/issues/1376

When attempting to automate deployment of machines via a setup key, only the first machine gets recorded as a peer, and each subsequent machine seems to connect but is only assigned the same IP address as the first peer and is not accessible.

We are using netbird to have different groups of rental laptops on vpn for remote management. A scheduled task runs one time after the machine is imaged to run "netbird up --setup-key ", which seems to be working correctly but results in the above behavior. We are very interested in switch to netbird for our vpn, since currently about half of the hands-on time for preparing each laptop is installing and configuring Hamachi, and being able to use one key for as many machines as needed would be perfect for our use case.

NetBird status -d output on the second machine:

PS C:\Windows\system32> netbird status -d
Peers detail:

The FQDN here is identical to the first machine, despite the second laptop having a different hostname. What are we doing wrong?
