Netflix no longer streaming

Thanks for all of your help and input on this iTinkeralot! I have my T-Mobile Gateway connected to an Asus ZenWifi mesh system (3 nodes). All of my devices are connected to the Asus mesh wifi network.

That said, I had already tried connecting my devices directly to the gateway and that did not help.  The behavior is the same whether I'm connected directly to the T-Mobile gateway or I am connected to one of my mesh nodes. 

I also tried multiple different DNS providers, including Cloudflare, Google, Quad9 and some others (both connecting directly to the T-Mobile Gateway and via the mesh network). Again, there was no change in behavior regardless of what DNS provider I was using.
