Server disconnected message and certificates
TB 91.5.0 running on Ubuntu 20.04.
When I launch TB I usually see a message (that does not stay on screen for long so I cannot copy it) to the effect that it cannot connect to a certain imap server. Now, the server mentioned is really just an alias for the canonical name of the server. I may have used that alias in the past when defining an email account, but I have since changed the server name to the canonical version. Thus, the only place left in my installation that refers to that alias is in the certificate manager of TB. I see there a list of 4 certificates, of which 3 show the alias for the server, the canonical name in the Certificate Name column, and have a lifetime of permanent.
I do not see any specific problems in sending or receiving mail. None of my plugins refer to any servers.
Now for my questions: 1) Is that initial message about not being able to connect to a server likely to be due to the Server names for the certificates? 2) On the assumption that there is a relation between the messages and the certificate, what is the impact of the failure to connect? 3) And finally, on the assumption that the certificate configurations ought to be corrected, how to do that, given there is no Edit option in the Certificate Manager.

Try looking in the activity manager (it is in the tools menu) and get the exact message shown there about when was not connected to.
Otherwise open the error console (ctrl + Shift +J) and look through the entries there, the error should be in there, along with a lot of garbage usually. But without knowing exactly what the error is guessing is what we would be doing.
Open the troubleshooting information on the help menu. Under the mail and news accounts is there no reference to the server name?
Do you have a calendar on that server configured(but apparently not working)?
The exact message is: Server imap.mydomain.com has disconnected. The server may have gone down or there may be a network problem.
The error console has no entry at all obviously corresponding to the message above. Here are some errors in the console that are around the right time, but I have no idea if they are related to the issue: 16:46:46.225 Unexpected event profile-after-change URLQueryStrippingListService.jsm:224

If I enable troubleshoot mode, the same message appears at startup, as well as the same two error messages in the console.
I repeat that that ONLY place where imap.mydomain.com occurs is relative to the certificates. It is nowhere in the email accounts, calendars or news feeds and I have not set up any chat account.
While I have calendars set up, they work fine and have nothing to do with the imap.mydomain.com server.
