Apache throws the following errors after attempting to set up ssl certificates:
[ssl:emerg] [pid 30907] AH02572: Failed to configure at least one certificate and
I ran into the same problem. Now I resolved it.
You included
/private/etc/apache2/extra/httpd-ssl.conf
in httpd.conf.
So you still need to set following keys in 'httpd-ssl.conf'
SSLCertificateFile "path to your crt" SSLCertificateKeyFile "path to your key"
Hope it is helpful.
