outgoing error message

My previously stable Thunderbird install stopped sending outgoing messages a few days ago. I get a "Sending of message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.charter.net timed out. Try again." error message. Charter says not their problem because I can send from their email web site. I've disabled anti-virus, tweaked SMPT settings to match the recommended settings, and tried just about every combination of security and authentication setting there is and got nowhere. If I turn authentication off, I stop getting the time out error and get an user name rejected error. I am out of ideas.

I think I got it. I have a decade old profile in Thunderbird that I used temporarily during a motherboard/ hard drive swap out. The accounts were outdated, so I set-up a new account. When it asked, I let it auto-configure the router settings just to see what it came up with. Those settings worked. I went back to my current profile and changed the settings to match, and they worked. there are two differences from what I had, 1) instead of smpt.charter.net, it was mobile.charter.net. 2) instead of the default port for SSL/TLS (465) it used 587. The question is why a working configuration suddenly break?

The fun of computers.

Thanks to the people that tried to help.

Try with mobile.charter.net, 587, STARTTLS, normal password, email address.

Settings depend on the domain of your account:

https://www.spectrum.net/support/internet/email-settings/#/mobile-email-settings

Been there, done that multiple times. Just as a clarification, this is a PC install, not mobile. As a long shot, I want to try and delete/re-enter the smpt. password, but all the tutorials on-line seem to be out dated and the menu options don't match my version. I am running version 140.1.0esr

Settings/Privacy & Security, Saved Passwords, to remove and edit passwords.

The settings in the Spectrum link apply to mobile and desktop apps.

I was at that page a few times during one of my banging my head on the keyboard sessions. It does not have an entry for the smpt server. Should there be one? I may have deleted in already. I have tried so many different things, I don't remember what I have or haven't tried already. I probably have at least a full day of time fighting this over the last 7-10 days. The frustrating thing is that it was working fine, the suddenly it was not.
