I just got it working. The URL of my cPanel was not working, however, I clicked on webmail on my cPanel and copied that URL (mail.antagonist.nl) omitting the https etc and it worked!!!! Finally. This is our entire company email with 7 of using Gmail in this way so it's such a big deal we are back up and running. Thank you so much!

I've been looking a solution for weeks. As soon as I saw yours, I had an 'aha moment' as I remember always using that server name in the past. Thank you

Oh, damn. What is your domain name?
What hosting company are you using?
What are your current Gmail settings?
