I’ve seen this happen when your host (which you pass in as httpaction) has the scheme (so “http://”) in front of it. Your host should strictly be the domain like “www.google.com” not “http://www.google.com” or “www.google.com/hello-world” or “http://www.google.com/hello-world”.
Keep it just the domain.
