Starting development server at
After clicking on the above server link , The site can’t be connected issue comes up.
Please help me with it.

You have to run the server on one terminal and then in another terminal you have to open the FTP service. The IP address you have typed is used to avail FTP service on a terminal. After these two processes are executing simultaneously, you can do file transfer using terminal of your PC or by using FIleZilla application.

Is your problem resolved, if so how did you do it.
