Hi

I am trying to add web service reference using Web Service task and the web service is having https protocol. after adding url in Http Connection manager i can successfully connect to server. I tried it using TestConnection but while loading WSDL getting an error 

TITLE: Web Service Task
------------------------------

SSL certificate response obtained from the server was not valid. Cannot process the request.


------------------------------
BUTTONS:

OK
------------------------------

Do i need to install any certificate?

We had similar issue faced in Script Task where there was logic downloading file.

In our case what we did was to use Webclient class  based logic instead of connection manager to get job done

Something like on the lines of below
