Netflix no longer streaming

I'm in a suburb of Dallas, TX.  My gateway is the Sagecom and the firmware version is SGJi10105-1.1.52.  I've had this gateway for 2-3 months and it shipped with this firmware version.  The Android Netflix app on my phone functions and I am able to access Netflix via browser on a Windows 11 PC.  Netflix menu pages load slowly on the browser but it does appear to stream okay once you get that far.  Other sites load without issue.  In a new and possibly unrelated twist, the gateway has lost internet several times in the last 12 hours, though connection to the cell site was still shown as excellent.  Most of this was between 10 PM and midnight last night.  The timing makes me wonder if this might have been related to maintenance, though that sort of activity should normally occur between midnight and 4 AM.
