The error means your email provider's server is not properly configured and exposes you to the LogJam attack. Thunderbird is trying to prevent that. https://weakdh.org/

As a workaround you can install this add-on. https://addons.mozilla.org/en-US/firefox/addon/disable-dhe/

Note, this will allow you to connect to the server in a secure way, but it doesn't address the underlying problem of the server still being vulnerable.

Check this article if you are having difficulties installing the add-on for Thunderbird. http://xenos-email-notes.simplesite.com/416814616
