You're right, this is a vague error message, I'd like to see that improved!
It looks like the name of your server does not match the name of your certificate (I see an
unrecognized name error when hitting it with
openssl s_client -servername www.lightspeedmarketing.com -connect www.lightspeedmarketing.com:443 -state -quiet) - this SSL handshake error prevents the cards crawler and validator from fetching the page.
You'll need to ensure that your ServerName and/or ServerAlias are set correctly. There's more detail on this issue in this thread - it's a Java security design choice.
