Get Http Module to work with HTTPS

Hello,
My project use http module to do GET/POST to a https server. Here is the sample code:

        void WWW::request(string url, WWWForm f, std::function<void(WWW*)> pOnHttpResponse){
            	TSharedRef<IHttpRequest> HttpRequest = FHttpModule::Get().CreateRequest();
            
            	HttpRequest->SetHeader(TEXT("Content-Type"), TEXT("application/x-www-form-urlencoded"));
            	HttpRequest->SetURL(url.c_str());
            	HttpRequest->SetVerb(TEXT("POST"));
            
            	FString fs(f.getPost().c_str());
            	HttpRequest->SetContentAsString(fs);
            
            	HttpRequest->OnProcessRequestComplete().BindLambda([&, pOnHttpResponse, f](FHttpRequestPtr HttpRequest, FHttpResponsePtr HttpResponse, bool bSucceeded)
            	{
            		if (!bSucceeded) {
            			GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("Request failed"));
            		}
            		else
            		{
                               GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("Got something here!"));
            		}
            	});
            
            	HttpRequest->ProcessRequest();
        }

Basically, i want to send a form to the server and get a response back. The code above works flawlessly on PC , no problem whatsoever. When i deploy my game to Android , the request always fail. When i switched the url to something like “http://something.com”, i got a response. Switched it back to my https server, or any https page, and it will fail. I tried the solution posted in this thread : Using Http Module on Android - Multiplayer & Networking - Epic Developer Community Forums , but no luck. My UE4 version is 4.7.6 .
How do i solve this ?

Hello John, I am assuming you have solved this problem? Mine http request for https server works on PC but fails on iOS. Thank you.
