Got it. We will investigate the problem.
Can you tell me more information about browsers that cannot connect? version and platform.
I think ssl negotiation failed between the browser and server about encryption cipher to be used. please try change the ssl cihers setting for the ssl listener manually to
ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP, which is Apache mod_ssl's default, then restart the server, see if it help.
The certificate problem probably has something to do with the SSL session cache. For some reason, some necessary certificate information has not been sent, maybe due to SSL session cache. We will find out. :-)
