I had the TV Everywhere source working, with some quirks, then it suddenly stopped working altogether. I tried restarting the service, rebooting the server, and reinstalling Channels. Same results every time now. When I attempt to add a source using my Spectrum credentials, I get an error dialog with "chrome auth_timed_out", and an image containing a screenshot of the Spectrum logon dialog containing an error message: We're sorry. Something didn't work quite right. Please try again later. ELI-9000
I also tried this with Edge with the same results (including the chrome auth_timed_out message...)
