Failed to connect.
When I run Thunderbird I'm getting the message "Failed to connect to server. mail.supremecluster.com". This was a mail server at one stage but now all my email accounts are on a completely different server. All there configs are correct and I receive mail but this message keeps popping up and I can't find it in any of the settings.
Chosen solution
I deleted an account that no longer had a server. It was on mail.supremecluster.com previously but had no longer had any visible info about that domain. Surprisingly, the warning message has stopped.

Was it a calendar on the sever perhaps. Folks appear to forget that calendars use authentication.
Thanks for your reply. I looked at calendar properties. It did not mention mail.supremecluster.com I turned the "Home" calendar off anyway but the error message still appears.
