Windows Sample hangs #318

Closed danewalton closed 1 year ago

danewalton commented 1 year ago

The Windows sample for the middleware seems to hang currently.

From @vaavva who investigated a bit:

It will eventually run after 5-10 minutes (and after enabling ip config logging the long wait at the beginning is it trying to do the DHCP process, but never succeeding), but it won't connect to my hub, probably since it doesn't properly get the DNS resolution.

Setting this to 1 enables some extra logging to see what's going on. With that additional logging on, this is the printout I get:
