Probably memory access violation when reading Headers, although I'm guessing slightly as the function is not documented.

int MakeHTTPPOSTRequest(const SCString& URL, const SCString& POSTData, const n_ACSIL::s_HTTPHeader* Headers, int NumberOfHeaders);

I'd expect the Headers parameter to be the address of an array of headers, which is why the NumberOfHeaders parameter is needed.
In your code you pass the address of a single header, but you tell the function that there are 2 headers to read, when the second non-existant header is read an access violation can occur.

Suggest setting NumberOfHeaders = 1

If you actually need 2 headers then

const int numberOfHeaders = 2

n_ACSIL::s_HTTPHeader HTTPHeaders[numberOfHeaders];

HTTPHeaders[0].Name = "Some-Header";
HTTPHeaders[0].Value = "123";

HTTPHeaders[1].Name = "Some-Other-Header";
HTTPHeaders[1].Value = "456";
