TVE Spectrum now failing for some NBC Sports channels that were previously available

For the last several weeks I have had access to some of the regional NBCSN channels. I am using Spectrum login for TVE.

But just in last coulpe of days, it seems that I am unable to authorize these channels. I get message "authz retries failed" when trying to rescan (see image below).

But unlike the other channels where I see the message "login not supported", Channels still sees these "authz retries failed" NBCSP channels as available and attempts to schedule recordings using them.

As a result, I have had a few recordings fail.
I have the latest build as of today (2019.08.15.2304).

Any suggestions?

Does it work on http://stream.nbcsports.com/rsn/nbcs-washington
