How to connect an iOS application to SUP 2.1.3 through Relay Server using Port 443(SSL)

Dear Experts,

I am developing an iOS application Using SUP 2.1.3 - relay server (SSL).

I am able to connect it through port 80 - relay server.

However, the app does not register when i use port 443 (SSL)

Do we have to write extra code for registration than we write normally when we connect the app through relay server port 80?

Please Note: Required Certificates are also installed on device.

Any help is appreciated.
