New to EC2: Unable to connect to host error


It might be that your corporate firewall is not letting out SSL based traffic. If that is the case you have two options:
1) change the environment variable EC2_URL to http://ec2.amazonaws.com/
2) ask your administrator to allow external access on port 443
If you use the non SSL http://ec2.amazonaws.com/ URL you should be aware that although your requests are authenticated, i.e. no-one else can perform EC2 calls as you,  they will not be confidential, i.e. someone could view your requests.
