Adding Gmail Account to Thunderbird NOT Working

I've tried to confirgure my Gmail account to Thunderbird multiple times recently, but not successfully getting it figured out. I'm always given a 400 error message and I can't figure out the root cause. I've updated and redownloaded TB and reset my Gmail password.

I've included screenshots to verify what I've got currently setup in TB and my Gmail settings. Anyone have this problem or have the solution? I have 3 other mail accounts that are not hosted by Google that work fine.

Are cookies accepted in TB Settings (not browser settings)? It's necessary for OAuth2. Or, using a VPN?

For those wondering, it seemed to have been that my TB cookies were off. This was the problem.
