[CalendarServer-users] SSL Ciphers

I've setup the latest version of CalendarServer on Wheezy and everything works fine with the exception of SSL functionality. The public, private and CA cert files are configured as described in the default configuration and they are accessible by CalendarServer. Nothing can connect to the SSL port, and neither the access or error logs show anything. Phython2.7 is listening on the SSL port. The only thing I could get was from Firefox giving the error: (Error code: ssl_error_no_cypher_overlap). I tried setting the SSLChiphers key to ALL in caldavd.plist but nothing happened.
