Calling HTTPS SOAP API

Hi,

i created an application that calls a HTTPS SOAP web service but i get an error message that connection is terminated by the HTTPS server, i blieve this happens because my application doesn't implement any security yet. Could you guide me how to solve this issue ?

SOAP URL is like : https://......./api/aaa.svc?singleWsdl
I attached a snapshot of  settings of the web screen that calls it.

Hello Bil,

To help you, i need more information. 

Are you calling an external web service provider?

Can you open the WSDL in your borwser?

Is the SSL certificate valid?

Do you see any error or failure message in http://your_platform/ServiceCenter error log and general log?

Regards!
