Paramount plus blocked on your network

@XfinityJamesC​ Thank you for getting back to me. When using the app on a cellphone with mobile data it works no problem. When using any device out the wifi in our home it will not work. We just get a black screen with a constant loading wheel. We have two televisions on using amazon firestick to stream. This happens on cellphones as well, if connected to home internet. It seems to be something with the network blocking the app from running. 

Thank you for clarifying what was happening, @user_j4fg7c. Have you checked the admin interface on your router to see if any filtering or firewall settings were in place? I have seen situations where a previous attempt to block a malicious website at one point ended up blocking a legitimate website down the road.

If you are using an Xfinity Gateway, you can access these through the Xfinity app on the WiFi tab under "Advanced Settings". If you are using a personal router, the admin page can usually be accessed through a browser window by going to 192.168.2.1 or 10.0.0.1. If you've already ruled this out, or if you aren't seeing any blocked sites listed, please let me know, and we can look into this further.

I was able to turn off adblocker for both amazon firesticks in the house and restart the router to apply the settings. This has not changed the issue. For reference I am using a netgear CM700 modem and a netgear xr1000 router. If there are other settings on the admin portal I can try please let me know, thank you!

Thank you for all of your help. I went back and disabled adblocked every device on my network that wasn't properly named as something I know. Both of my firesticks are now working properly and I can watch shows and movies again.
