TV Everywhere YTTV Connection Not Secure

[DJenner8]

When I try to connect a TV Everywhere Source, YouTube TV, Google complains that the connection is not secure. It doesn't like the certificate. I have tried 3 browsers: Firefox, Safari, Chrome. On macOS 12.7.2 Monterey. (all browsers up to date)

The Google error is:
Google couldn't sign you in
This browser or app may not be secure
Try using a different browser. If you're already using a supported browser, you can try again to sign in.

I am using a Western Digital MyCloud Pro PR4100 with OS5 Firmware 5.27.157 (up to date).
Channels DVR 1.0.7 (up to date)
Server version 2024.01.08.1431 (up to date)

What's wrong with the certificate? How do I fix this problem?

Is There a Fix for YTTV (browser or app may not be secure)?

I've searched the forums and haven't come across a fix for this. I'm running v2023.09.19.0804 on a Synology NAS. I've updated Chrome through the Troubleshooting tab and switched from Cloudfare as my DNS host...still can't login to add YTTV as a TVE source. Anyone got this figured out? Diagnostic Logs sent.
