Unable to connect to Stream Engine through goCoder SDK

Hi,
I was currently using trial stream engine and trial goCoder SDK, it was working fine. Now I have purchased Wowza stream engine license, but I am to publish live stream. Can I connect my purchased stream engine with my trial SDK?

If not, then how can I purchase goCoder SDK?
If yes, then why can’t I connect to the host?
I am using host “http://ec2-13-229-107-169.ap-southeast-1.compute.amazonaws.com:8088”, it is working in browser but I am unable to connect it with goCoder SDK.
