socket.io not coming up in my SSL site

Hi
In my SSL enabled server, socket.io is unable to communicate back to Drupal site. Both node.js and drupal are in the same server.
and all the components of npm are of latest version.
I gone through all the existing issue list and tried with different possible values for nodejs.config.js file. Nothing worked out. Please help

I see this error in chrome:
GET https://localhost:8080/socket.io/socket.io.js net::ERR_CONNECTION_REFUSED
