Over the last 6 months or so, failures to send email were occurring sporadically with Thunderbird for my wife's account with Comcast. Hitting the retry button on the popup or clicking the x button would at times result in sending the email. Presently, this does not work, nor does the option of entering the password when the prompt occurs during attempted sends.
Current version of TB is 115.2.2 (64-bit). SMTP port is 465, normal password and SSL/TLS and protocol is POP.
With mailnews.smtp.loglevel set to All, the console repots the following:

I have other email accounts that work correctly with comcast as POP and Imap in my accounts on several Windows 11 computers. My wife's account otherwise works correctly with Comcast's email tool accessed through a browser. In the log file above, "username" is substituted for the actual user name.
Please interpret what is happening and advise what actions might be appropriate to resolve the problem sending email with Thunderbird.
