TVE authorization failure

I've had TVE working on YTTV for quite some time without any issue. Now it stopped working on all channels. I am using a Synology NAS for Channels server and AppleTV for the channels client. I deleted the YTTV source and tried to add it in again and I get the following message.

I am using a google family account with 2FA not enabled. I have also tried logging into https://nbc.com/live and login to authorize TVE access. That works fine.

How do I get Google to recognize my NAS as an authorized device?

Try to click-and-hold the Sign In button for one second after entering your YTTV login

I did that and it spins for a few seconds then produces a message "context canceled".

Please submit diagnostics and email support

I submitted diagnostics and emailed support.

Is there any other things I could try or data to collect to figure out why I can't get YTTV to authenticate my NAS? Thanks!

Did you try rebooting the NAS?

I rebooted the NAS and that fixed it. Now I can quit using the crummy YTTV ATV app and go back to the Channels GUI. Thanks!

This should always be the first step of trying to fix anything.
