Hello, I cannot send emails in Thunderbird. The email is configured properly, and the SMTP server as well. I tried without VPN and antivirus and it still does not work. I am on Windows 10. Here is the message I get. Could you please help?

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.etud.univ-paris8.fr failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.
