iCamera 2 Help

Hi, I have 3 Cameras from Xfinity I created smart apps and device handlers using the instructions give in this post

I added them and actually was able to see the video once, but it only worked for 5 seconds, is there anything I am doing wrong in the camera settings, a firewall, I entered the video IP and port.

Does anyone has experience and have made this work?

Thanks in advance for your help.

I am in the same spot. I have the device handlers and smart app, just now need instructions on adding the cameras. Can anyone weigh in on this?
