Tried manually setting DNS to all 3 listed in the article - no change when using all 3, sadly. Firewall was updated as you recommended and still no change. Only thing I haven't been able to do is try port forwarding (my router requires some goofy-ass 3rd party app on a smartphone to set port forwarding)
Really stumped about my issues here. Again, if I immediately run Plutonium after restarting my PC, I don't run into this issue at all.
