When I use https protocol instead of http, I just receiving an error message at jobdone with result false as
"errormessage: javax.net.ssl.SSLPeerUnverifiedException: No peer certificate, httputils2service=null etc...
Seems like a certification issue. Does this site have a valid certification? If not then you can use HttpClient.InitializeAcceptAll instead of Initialize.
If you are using HttpUtils2 then you will need to add the code modules instead of the library and change it in HttpUtils2Service.
