What am I doing wrong? Thanks. A: I suspect your issue is that you haven't specified the correct host header to send to the server (which is used by name based virtual hosts to determine which site to serve). You are currently sending: > Host: server.example.com Which is probably hitting the non SSL site, try: > Host: secure.example.com You can specify the host header in curl with the --header or -H option, for example: curl --header "Host: secure.example.com" https://server.example.com You should also ensure that you are hitting the correct IP address for the SSL site, if server.example.com is pointing to a different IP than secure.example.com you may need to explicitly use the IP for secure.example.com or override the DNS resolution (which can be done with curl --resolve option). A: I have the same problem, but the solution of specifying the host header doesn't work for me. I think the problem is that the SSL handshake is done before the Host header (or any HTTP headers) is sent. So the server doesn't know yet that I want the secure.example.com virtual host and presents the default certificate for server.example.com. There are two possible solutions: * *The server is configured to accept SSL connections for secure.example.com on a different IP address. Then use this IP address in the curl command line. *The server is configured to accept SSL connections for secure.example.com on the same IP address as server.example.com. Then the SSL certificate must be a wildcard certificate or a certificate with several hostnames in the SubjectAltName extension. See http://httpd.apache.org/docs/2.2/ssl/ssl_faq.html#vhosts for more background information. A: This worked for me curl -k https://yoursite.com -H 'Host: otherdomain.com' The -k ignores certificate errors
