I had set up a local modded server to play with a friend, and we had been playing for a few days. For some reason, today when we tried logging in to the server, Minecraft gives an error message stating, " java.net.ConnectException: Connection refused: no further information:". Since I am running the server from my laptop, I am able to connect directly by using the "localhost" address. However, whenever I or my friend try to log in using my IP, it refuses connection. It's frustrating, as the server had been working a couple days ago, and I haven't done anything to the server properties or folder that it's contained in. If anyone knows a fix, please let me know. Thanks in advance.
