I made no changes since my original post. Frankly, I'd given up on it, not willing to waste any more time on it. HOWEVER, it randomly started working last weekend. Connects fine and fully controllable via the app. Comcast must have pushed an update?

SAME issue here!
My Carrier Infinity Touch will connect to the WiFi just fine, BUT WILL NOT connect to the Carrier Server through the XB6 Comcast XFi router.
I've spent about 7 hours on this now, talking to several people at Comcast who blame Carrier, talking to Carrier Technical support who blame Comcast, and talking to my Carrier dealer who says that it should be a very straight-forward set up and has never heard of this issue before with other customers.
I have received the trouble-shooting PDF from Carrier and made sure all of the recommended settings are correct. I've verified those settings with Comcast. Still... no connection to the Carrier Server.
Now, the thermostat WILL connect fully to the wifi AND the server if I use my Verizon MiFI, but clearly I don't want to keep doing that, I want to use my home wifi that I'm paying comcast for. But, this does indicate that it is certainly an issue with Comcast and/or the Comcast router.
The last thing I was told by Carrier Tech Support is that they've never heard of this issue and that I should call my Carrier Dealer and request a TP Link Router, which I just did. My dealer says that the TP Link Router doesn't apply to this Infinity Touch Router.
