Some of these tests appear to be a different issue, as far as I can tell. Northernlite/Darthvixen figured out the issue for Darthvixen. Most of the rest of you are having issues midway through your connection test.
Typically I’d split this off into multiple threads, but I have a suspicion that even if Darthvixen fixes their issue, they may run into the issue the rest of you are having. I wonder if an alternate connection like a VPN works around each of your issues?
