title: Cannot reach socket server on AWS EC2
body: <p>I am trying to run a socket server on an Amazon Web Services EC2 instance. The socket is able to run just fine on it's own, and telnetting locally on the instance can connect, but trying to telnet to the socket from the outside is failing. I have gone into the security groups to ensure the ports I am using are open for both TCP and UDP (though the socket server has been configured for TCP). Is there something else I am missing?</p>
