And you've verified that the DNS record has the correct IP address? I would check the web server config to make sure it will respond to that name. See if there is anything in the access or error logs.

connection timeout doesn't sound like ssl problem to me. is the webserver actually running? i think i read nginx in a different post, you might look for a running nginx process using

ps aux | grep nginx

If it is running, is the connection working with normal http:// on port 80?
