Fios and Discovery, Food, and DIY

I am just curious if Discovery and Food and DIY is supposed to work with Fios over TVE?

I get the following errors with the channels. Context Canceled, or Context Deadline Exceeded.

I know way back it used to work, but now I can't get them to scan.

There have been some TVE fixes in recent server updates. If you’re not already I’d recommend updating to the latest prerelease and see if it starts working.

Not sure if Fios has the same issues as Xfinity when authorizing channels.
I had to delete my chromedata folder to get my Discovery Network channels back after their auth expired.

I can't figure out how to get there...is I'm on Nvidia shield.
