Because of the recent "authz retires failed" error on Spectrum TVE, I removed the Spectrum source and re-added. This worked, but as I have seen before when adding Spectrum, there were about 10 channels that didn't add, due to the error "403 you've exceeded the maximum number of streaming sessions". In the past, I would just rescan those channels every few hours, and eventually they would all scan successfully.
So, I'm at that point now, and a few channels have rescanned, but today I ran into this error when trying to scan the remaining:
TypeError: Illegal invocation at reactValueSet (tveloginhelper.js:193:28) at spectrumLogin (tveloginhelper.js:40:5) at tveloginhelper.js:259:5
For the channel that returned this error, I was able to go their website and login in with my Spectrum credentials, and watch live TV there.
Had "auth retries failed", so I updated to 2020.11.24.2138 this morning. Error still occurred. I then removed Spectrum as a source and when I tried to add it back, I received a splash page after entering my credentials "...Auth failed for Spectrum: TypeError: Illegal invocation..".
