I've been unsucessfully trying to get a real SSL certificate to work with Zimbra and decided to go back to a self-signed certificate set, however I've apparently broken something so that even the self-signed cert will no longer work.

zmcreatecert
cmcertinstall mailbox
zmcertinstall mta ssl/ssl/server/server.crt ssl/ssl/server/server.key
zmtlsctl mixed
tomcat restart

These commands complete without error and show what I would expect them to show. I tried deleting the tomcat keystore file and letting it be recreated.

Firefox displays the following message when trying to connect to port 7071. "Firefox and xxx.xxx.com cannot communicate securely because they have no common encryption algorithms."

Ideas?
