Originally created by @maddie on GitHub (Sep 6, 2021).

Using Tailscale v1.14.0 here, and when I try to join the network, tailscale up hangs and logs printed by headscale:

Sep 06 06:38:42 headscale headscale[51960]: [GIN] 2021/09/06 - 06:38:42 | 500 |    6.694432ms | 192.168.103.253 | POST     "/machine/8220a4cce5513fc662404da43020abe2eabc3def64d5f38a362b60689466a51d/map"

It seems that headscale fails to get the machine IP here:

123f0fa185/machine.go (L80)

Any pointers?

Are you still having this issue? Where you connected to the official Tailscale.com service in that machine before?

Sorry, been busy.. I'll test again when I have time, and re-open if there's still issue.

FWIW the node was a freshly installed Ubuntu 20.04 and Tailscale.

The root cause is an expired pre-auth key.
