I use my iPhone to send head tracking UDP packets from SmoothTrack to OpenTrack.
Until a few days ago it worked fine. Now it works for about a minute, then SmoothTrack aborts with “Can’t assign requested address”.
When I connect the phone to my local machine it works fine. The phone is either on 2.4 or 5 GHz wifi.
Can this be a ZeroTier connection problem?
What I can do to investigate?
