When I try to add Youtube TV to my TV Everywhere sources I always get a timeout. I've tried it with bot chrome and firefox, Any help would be appreciated.
What are you using as your Channels DVR Server?
If you run the sever off a Nvidia Shield, it will not work with YTTV.
Other wise, things such as having 2FA on your Google Account will case i tot not work.
There is a YouTube TV thread here:
