my Thunderbird just upgraded to 38.2.0 and Connections to my IMAP server stopped working.

It says in the status bar at the food of the program. Connected to mail.Server.com and just sits there with a blue spinning icon.

I can prove the server is working by using my iPhone/ipad and I created a account in Mac Mail and it works fine so It seems to be related to thunderbird and the new update. Its connecting over ssl port 993 using password.

Open the error console from the tools menu. Clear it and then check for mail. What error messages appear?

well it comes up with Timestamp: 26/08/2015 13:25:09 Error: An error occurred during a connection to mail.server.com:993.

The server certificate included a public key that was too weak.

(Error code: ssl_error_weak_server_cert_key)

using Apple mail seems to work

OK Fixed thanks.

Cert had expired so issued a new one with a stronger key. I guess the new version aggressively checks the cert.

It aggressively (your words) checks the length. Keys less than 2048 bits are rejected.
