Please make sure you run latest version of OrangeCD (6.5.0). Amazon frequently changes its API schema which makes old versions of OrangeCD unable to use its services. But the most recent version works fine with Amazon services - I just verified it.

If you're using the latest version and still have this problem, there's two more things to check:

1) Make sure your system time AND time zone are correct. Amazon services are sensitive to client's system time.

2) Make sure your firewall doesn't get in the way. When in doubt, try disabling firewall momentarily and see if it fixes the problem.
