where i am wrong and if you have any proper code or details then give me.

Answer 1

If this is a MySQL database in local server user "localhost" for server IP as georgi-it also told. But if this is an external database first try to open a telnet connection on dos-prompt to see if there is some firewall block or something like that:

telnet 216.14.120.105 3306

if you don't get an error message and see a blank page then it means you can reach mysql server
