Amazon EC2 - Windows 2008R2 instance not reachable

Question

I just set up my first Amazon EC2 instance (Windows 2008 R2 server) and istalled a jetty 9 on it. But i can not reach it with it's public IP (as shown on the desktop of that system) on port 8080.

I can reach: "http:// localhost:8080"

But i can not reach: "http:// publicIP:8080"

I allowed the port in the EC2 Security group. See the screenshot:

I can even ping the "publicIp" from outside, but can not reach the jetty on port 8080.

I'm not sure where the problem is: Is it a configuration in windows, jetty or the EC2 Management console?

Answer 1

确保端口在Windows防火墙中打开。

Answer 2

First obvious problem might be that your security group isn't assigned to that instance. Check that this one is the group your instance is using on the dashboard.
