This started last night with some "maintenance" that wasn't announced which was supposedly to fix the constant problems connecting to the cameras from the webportal. I had to then reboot my three routers to get it to work from my end.
It was working for a couple of hours, which was better than before. It has been down for some time now.
I was having the same problem and connected with customer service CHAT; was told Comcast is doing system updates and should be back online a couple of hours. Was told that my home system was still being monitored by Comcast Central. It would have been nice if home security customers were notified in advance that upgrades were being performed today, or AT LEAST a pop-up message when you try to log in on your phone or PC.
Sorry for the inconvenience, we’re aware of this XFINITY Home issue and are investigating.
I was told basically all we have is an audio alarm right now if some one were to break into our house. Just great, what am I paying for again? If you use your touch screen and go to Settings>Advanced Settings>Connectivity>Test Connectivty and run the test by hitting next, you'll see that both the Broadband connection AND Cellular backup are down. This is irresponsible.
