what are u trying to do? LAN only or using via internet? because using 127.0.0.1 works only on the same PC will not work on ur LAN. if u want to make it work on lan. make sure to use the local IP address provided by ur modem or router. if out side the network or over the internet. you must open specific port and use your public IP. or static IP address from ur ISP to make it work so others can connect on your server.
