Flaky scratch process when wifi is down [windows]

[guruofquality]

It seems that when the PC has a wifi connection that is disconnected but not disabled, the GUI is not able to consistently talk to the scratch process. There may be an unknown error, things stall, sometimes a connect error to the server. This may turn out to be a library fix, but it seems to only happen with the GUI at the moment (the self-tests for remote components work).

I suspect that the cause is a misbehaving network API call (possibly related to DNS) either in Poco, or windows itself, or something mishandled. It only happens with a disconnected wifi which is a good clue.
