AWS Latency in opening ports?

Question

I recently wrote a C# console application server and client, which I am demonstrating on an AWS EC2 Instance of Windows 2016 Server. It uses a special port I defined 9314 over TCP. I have added the port number and allowed addresses from everyone to inbound traffic.

When I run the application server on the remote desktop, it connects and listens fine on its internal ip port, or so it tells me. When I start my client on my desktop, and connect to the public ip and port I provide, it timesout always... Is this possibly because the settings haven't "sticked" yet?

*connects and listens fine on its internal ip port, or so it tells me* What is an "internal IP port?" Is it listening on 0.0.0.0:9314? ...or something else? — Michael - sqlbot, Oct 26 '16 at 23:51
You probably forgot to open the port in the AWS security group. — Michael Hampton, Oct 27 '16 at 06:31

You should allow 9314 port from windows firewall as well to access from your machine or disable windows firewall and try. Hope it will work sure.
