So I have run a server for 2 years and then took a hiatus while waiting for 1.8 to happen. Recently I tried to run a 1.7.9 server just to screw around for a bit, but for some strange reason it gives me an Unknown Host error. I know how to forward ports through my router and setup the server.properties file but my port doesnt appear to be open when its clearly setup to be open. I opened up the port 25565 on my Internal IP (IPv4) on my router and put the same in the server.properties file. I tried connecting 4 ways: 1. Through External IP 2. Through External IP :25565 3. Through localhost 4. Through localhost:25565 Direct Connect just keeps me stuck on Connecting to server for a few minutes then times out. I have a Netgear N600 router and its stupid easy to forward ports. Ive looked at some tools to check if the ports are open but they say they are closed, which I dont get. I have multiple devices connected to the internet but I know which Internal IP is mine because it clearly says my computers name right next to it. Any ideas?
