El Capitan?s Calendar app requires TLSv1.2 handshaking which calendarserver doesn?t provide.
That's surprising to me, because OS X Server.app doesn't seem to support TLS 1.2 at all. My 10.11 calendar clients are able to connect to my 10.11/Server5.app server.
Even a vanilla web page only supports the ancient TLS 1.0.
I've filed this as <rdar://23091611> which is duped to <rdar://21183904>, which is marked 'closed' so there's hope.
I suppose there may be some other element of the SSL handshaking that is failing, but googling the console log errors turned up a big discussion of how El Capitan/iOS 9 Calendar enforced some higher level of TLS, likely 1.2. Maybe it's that TLSv1.0 must *not* be supported. I don't know. What I can tell you with certainty is that the latest Debian version of calendarserver doesn't work with El Capitan Calendar for SSL connections. But proxying through Apache (properly configured for TLSv1.1 and up) works fine.
Cheers,
