FAILURE for Outgoing email. Possibly configuration problem using Thunderbird on Windows 11 64bit PC

@Nanoo_the_Dog 

Trouble with SMTP.  Use Thunderbird ver. 146.

Here are settings:

Server: smtp.comcast.net

Port: 465

SSL/TLS

Auth: Normal Password

my username...

WOULD APPRECIATE solution.

I've tried:

--turned off and on router, then tested "successful"

--rebooted PC

-- RESULT?  Just spins onscreen... not connecting to server.

--So THEN... get this message:
            Login to server smtp.comcast.net with username [username]@comcast.net failed.

            RETRY     ENTER NEW PASSWORD      CANCEL.

I'd much appreciate next steps to try.  Questions from you that I can attempt to answer.

What is the exact error message?  Many people have been reporting a problem with the smtp server lately, including myself.  It eventually works itself out.
