Hi there 🙂
In this quick tip I’ll show how to send a udp request to your Amazon EC2 server instance and then receive a reply from there. Simply put, you can use this to check if your AWS servers are online or not when player is logging in.
So what are we covering today? Well, we will write a simple UDP server in Node.js and run it on AWS EC2 server. This server will be listening on EC2’s IP on a specific port. Then in Unreal Engine 4, we will use the FUDPPing::UDPEcho method to ping the above server ip and port and see if we get a reply. Let’s get started.
