Thanks for making and attaching the log, it really is helpful.
It looks like you’re seeing the same problem as this thread, where Messenger is trying to connect to your local computer during the connection process. Feel free to read that thread if you want, but the conclusion was made that either older versions of Messenger Discovery or a Kaspersky product could be causing this to happen.
From my own (very limited) testing back in December, I’m not completely sure that I know what’s going on but regardless, Messenger isn’t working the way it’s intended.
Since the problem just begun, it could be due to startup timing (I bet rebooting could solve the problem temporarily), or some sort of cached value expired. Moving forward, if you are using Messenger Discovery or Kaspersky, I would recommend unloading them (at least briefly), to see if that solves the problem.
