XR1000v2 router not working with Paramount Plus application

I recently purchased an XR1000v2 router to replace a 10 year old Netgear router that was still working fine except that it suddenly stopped letting me access an email server.  I installed the XR1000v2 router and could immediately access the email server but now it appears to not allow me to stream video from Paramount Plus.  Very weird.  I have multiple Amazon Fire Sticks on multiple TVs and the Paramount Plus application on all of the TVs will open and run but when an item is selected to stream, the application never starts playing the video (never ending spinning progress circle).  When I log into Paramount Plus on my laptop computer, the same thing happens when I try to stream a video on my computer.  If I VPN to my office on my computer, I can stream video from Paramount Plus with no issue.

All of the Amazon Fire Sticks can stream video from Amazon and other applications installed on the Amazon Fire Sticks can stream video.  I just cannot stream Paramount Plus video on any Amazon Firesticks or on my laptop computer.

Any suggestions or ideas about resolving this will be appreciated.
