Unable to sign in to FaceTime on my Mac desktop

For the past 3 weeks, I have been unable to sign in to FaceTime on my Mac desktop. The action results in the message "An error occurred during authentication" and also my FaceTime Preferences are greyed out. I have attempted to resolve by following most of the advice I could find on this site such as "If you can't sign in to your iMessage account or FaceTime on your Mac - Apple Support" plus other advice on the wider internet such as changing my DNS entries to 8.8.8.8 and 8.8.4.4. I have tested without any firewall in operation, skirted my router by cabling directly into my modem and in desperation I have reinstalled the complete operating system but all without success. There is nothing incorrect with my Apple id and password which works perfectly well when signing into my Apple account or the App Store. Any new advice will be appreciated.

System

Netgear Router - Nighthawk R7000

Firmware Version

V1.0.9.26_10.2.31

iMac, macOS High Sierra (10.13.5)

If you can't sign in to FaceTime

Make sure that you can sign in at appleid.apple.com. Learn what to do if you forgot your Apple ID or forgot your Apple ID password.
Choose Apple () menu > System Preferences, then click Date & Time and select “Set date and time automatically”. Click Time Zone and make sure that the settings are correct.
Make sure that you've installed the latest software updates.

I have that exact problem and I have gone through the same approach mentioned by BMalcM. I don't understand why my FaceTime preferences would be greyed out as well. @JackLi88, that doesn't work. Anybody else have a solution to our problem? Why would the Preferences tab be greyed out?
