WebService on HTTPS

I have a web service provider on IS. The web service currently runs on HTTP. I’m trying to secure the web service, so I opened a SSL port. I have a server certificate on a keystore and SSL ports pointing to that keystore.
When I try to execute the web service what I get is a Connection refused error.
It seems like the port is not opened.
I’m newbie and I don’t know how I can configure a HTTPS port to work with my web services.
Thank you!

While creating WSD provider did you select transport as HTTPS. By default HTTP will be selected.

Try adding port (HTTPS) from Security > Ports on IS admin

Thank you very much M@he$h. It´s working!!!
