Thunderbird fails to find my present email account.
Installing Thunderbird on a new iMac M4 with Sequoia 15..1.1 OS. Thunderbird says it "failed to find the setting of my email account." I entered the correct gmail user name and the correct password. Any idea on what might be wrong and how to fix it?

I confirmed that there is no anti-virus in my new iMac and I have also confirmed that the Mac firewall is OFF. Any other ideas?
Thunderbird downloads the settings for and @gmail address from here https://autoconfig.thunderbird.net/v1.1/google.com
If it can not connect to that address it indicated you have networking issues on your apple product. Quite possible caused by a VPN. Some of them make a complete hash of anything that is not a web browser downloading a web page. Otherwise we generally look for antivurs products and their ubiquitous software firewalls, but you say you have already addressed that possible vector. but are you using some sort of locked down corporate DNS server that only contains local addresses or some such.
Seriously it is about 99.99% probably that your issue is not Thunderbird or any of it's settings.
