Can you not try doing a http get not https

It throws a SSS_INVALID_URL error saying

The URL must be a fully qualified HTTP URL

change the url to http:// instead of https://

Its throwing a SSS_CONNECTION_TIME_OUT error saying

The host you are trying to connect to is not responding

. I dont think its possible to access the server via plain http

Shame. I would have thought you are going to need to send over some sort of header.
