That code means that the resource that you are looking for has been moved temporarily to a different location. Your computer software is smart enough to be able to handle the redirect, but the method that you are trying to use can't use the location information that is provided by the redirect response apparently.
You need to use https://eneida.io as your target (which is where the request is being redirected to). Most sites use the https secure protocol now and have ceased using http.
Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.
