When you are trying to connect it should look somthing like this

http://192.168.15.1:8080

or what ever the–> PUBLIC <-- addy is- you are tryin to connect remotely from home or somthing right? private addys like the one shown only work if yor on the network, try without the port numbers. If it is like that it means anyone one the internet can connect (at least to the login screen)
