Keep getting message 'Configuration could not be verified' when trying to recreate Gmail account access

I'm on Mac OS 10.6.8 running Thunderbird 45.8.0 (highest version available for this OS). I successfully hosted a Gmail account in Thunderbird for years until I just recently changed my Gmail password. Then I was completely locked out of accessing Gmail from Thunderbird, even after successfully retesting that new password directly in Gmail. I then tried deleting the Gmail account from Tbird, and have since been attempting to recreate it. I'm now getting the 'Configuration could not be verified' error, regardless of which recommended IMAP settings I use, and even after trying the "Allow less secure access" Gmail option. I've looked at all of the Mozilla support forum suggestions for similar problems, but am now stumped. Any help you can provide is much appreciated!

Thank you, it's working now!! I spent hours yesterday going over all of the Google articles, and thought for sure I had turned on the option to use "Less secure apps," since I had tried all other relevant advice. However, I just checked again, and the "Less secure apps" option was turned off for some reason. So after turning it on again, I was able to successfully enter my Gmail password in Tbird and it finished populating my account. Yay!
