Outgoing SMTP failing for main server (tds.net)

Thunderbird Send and receive email

I am using TB 140.7.0esr(64bit) on a windows 11 desktop/ Starting 15 Jan at ~ 8pm, my outgoing SMTP email from multiple tds.net email accounts through my default server (tds.net) is failing with the following message: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 129.159.94.43 (129.159.94.43:587), connect error 10060." The outgoing SMTP configuration is: "Server name: mail.tds.net Port: 587 User name: john.randle Authentication Method: normal password Connection security: STARTTLS" I have not made any changes to that configuration. I am still able to send SMTP by switching to another email account/server (e.g. gmail.com). I have contacted tds.net and they say, not surprisingly, that it is an email client (thunderbird) issue. I am getting the same error on another desktop running windows 10 with TB 140.6.0 esr (32bit). Any suggestions will be appreciated. Thanks in advance.

Here is an A.I. generated response: Error 10060 in Thunderbird typically indicates that the program cannot connect to the SMTP server, often due to network issues or incorrect server settings. To resolve this, check your internet connection, verify your SMTP server settings, and ensure that any firewall or antivirus software is not blocking the connection. Yes, most email providers immediately blame the email clilent, regardless of where the problem lies.
