My setup fails to get direct connections in some cases while in others it works. Is there a way to debug this, e.g. see why it fails to get the direct connection in some cases?
My setup: 3 locations (Home, Office, Studio)
It seems that the OS doesn’t matter (working mainly on Win10 but same behaviour on my Raspberry Pi).
Home and Studio have the same ISP (office is a different ISP), can it be that this is causing a problem?
