Openfire Server behind firewall - only http

We made following settings and also set in Spark as Server port 7443, but the connection times out. If we set spark to port 5222 and open firewall it works. But we are not allowed to use something different as http. What ware we doing wrong?

HTTP Bind Settings

HTTP binding allows clients using the HTTP protocol to connect to Openfire.

Can Spark actually work over HTTP?

If it does, you still need to try the http binding without the firewall first to make sure it will work without that variable in place.

I don’t think it can, tried myself and was not able to get it working
