My minecraft servers have been running fine until I got my new computer. My servers will only run on my internal IP, and localhost. You cannot connect through the external IP even with Minechat on cellular, and my friends can't join the either. I currently have a desktop, and it is connected to Ethernet, and WiFi. I have been trying many solutions, and none seem to work for me. I realized that on my old computer it will run the servers fine when I portfoward the computer. Any solutions?
