title: Connection time out while connecting to EC2
body: <p>I am a new user of amazon web services and trying to learn to use the services. </p>
  
  <p>I used the getting started EC2 guide to create and connect to an EC2 instance (trying to be within the free usage tier). </p>
  
  <p>I am able to create the EC2 instance for both Linux and windows, but I am not been able to connect to the running instance. I followed the instruction given in the getting started guide but still not getting any positive results. I used the MindTree tool as well as the putty to connect to running Linux instance. For window server, I tried the RDP connection with the running instance. </p>
  
  <p>I am getting connection time out error in MindTree, putty, and window RDP on window instance. I checked the security setting of the instance and port 22 (ssh) was enabled for the Linux instance and port 3389 (RDP) was enabled for the window instance.</p>
  
  <p>Please help me resolving this issue.</p>
