Could not establish a secure connection to server with safari

Question

Safari tells me that it couldn't open the page, because it couldn't establish a secure connection to the server. However, other browsers (opera, firefox) can open the page. Also, there's nothing in the apache error log.

The certificate is selfsigned, and uses standard values. (seen here: http://www.knaupes.net/tutorial-ssl-zertifikat-selbst-erstellen-und-signieren/ )

ssl config:

SSLEngine on
#SSLInsecureRenegotiation on 
SSLCertificateFile /home/gemeinde/certs/selfsigned/gemeinde.crt
SSLCertificateKeyFile /home/gemeinde/certs/selfsigned/gemeinde.key
#SSLCACertificateFile /home/gemeinde/certs/Platinum_G2.pem
#SSLOptions +StdEnvVars

<Location "/">
     SSLOptions +StdEnvVars +OptRenegotiate
     SSLVerifyClient optional
     SSLVerifyDepth 10
</Location>

Answer 1

Had a similar issue and only working solution seemed to be to enable insecure SSL renegotiation (the second line commented out in your config sample). Seems that Safari fails to do safe renegotiation with client certificates, or something.

You can confirm that by setting Apache LogLevel to debug and checking if you see something like this:
