I have started a new Windows server instance on Amazon EC2.

The security group has the following rules:

Ports Protocol Source

22 tcp 0.0.0.0/0
80 tcp 0.0.0.0/0
443 tcp 0.0.0.0/0
3389 tcp 0.0.0.0/0
53 udp 0.0.0.0/0
-1 icmp 0.0.0.0/0

I am able to ping the public DNS server of the machine and i can connect to it using Windows Remote Desktop connection. However, when i put in my web browser the public DNS server, it fails to connect. Morever, I used filezilla and putty (and in both I loaded the private key .pem) but i receive connection timed out.

I disabled the firewall on both my pc and the instance (which I entered using Remote desktop connection).

Can you please tell me what I am missing?
