Pluto TV broken as on around 8/12/26

Pluto TV app quit streaming on both of my TVs (old Visio and new Hisense, completely different OS). XFINITY support refused to look deeper into issue, even though I told them Pluto works fine if I use my T-Mobile hotspot instead of XFINITY WiFi.  They insisted I go pick up a Xumo (which also has the Pluto TV app) so I did, and I installed it.  Xumo doesn’t stream Pluto either.  The issue is between XFINITY and Pluto could be a blocked port, a bad route, a blacklisted IP, etc but restarting my WiFi device numerous times (per X tech) isn’t going to help.  It’s difficult to find good help these days.
