Used tbird for my gmail for years with no problem. Uninstalled chromium browser and suddenly tbird was getting a 'connection refused' message. Tried everything. Completely uninstalled/reinstalled tbird. It made no difference. I get a username or password incorrect. (It's not). This sounds like the two factor authentification thing but I don't know how to fix it. I went all over gmail settings looking for the two factor auth thing and found '2 Step Verification' which is disabled. What happened and how do I get tbird back to working with my gmail accounts? ( I DON'T whant to reinstall chromium, thanks.)

Chosen solution

The first error indicates the ISP database does not have your mail prodiders domain information.

The second indicates an in ability to connect using the credentials used.

Given Google is in the database, it tells me your firewall of blocking something like Thunderbird or the ports or the domains necessary ie Thunderbird.net and gmail.com.

have you tried restarting your computer in safe mode with networking and seeing if Thunderbird works?

Rebooted system (Linux Mint 14 - 64 bit) and tried tbird with nothing else started. It made no difference. Same error message when I try to set up the gmail account. "Configuration could not be verified - is the username or password wrong?". If I go to manual config for account setup I get the additional msg "Thunderbird failed to find the settings for your email account." This sound like the symptom for the 2 factor auth failure in another question but there was nothing about how to fix it.

   Can log on account readily using web interface.  Anything I should try?

Thank you, thank you, thank you! I reset the firewall on my DSL modem and that fixed the problem.
