Getting a "Cable provider authentication failed" on many Discovery TVE channels with FIOS. My season passes of Gold Rush and Bering Sea Gold were missing and I discovered this.
After trying to refresh source and download prerelease betas - I even deleted the TVE source and same error. Looks like some of the Discovery owned networks are passing authentication but do not work (AHC, Destination America, Motortrend etc)
• FIOS credentials work on Discovery website and Discovery app
• Using WD PR2100
• All green with troubleshooting checklist
