What is there to understand? Change your connection string to connect to the IP address of your server machine.

What he meant is that you have to change 127.0.0.1 to your own server. 127.0.0.1 is home. Is the DB on your machine, or on a remote server ?

thank u very much but as the modem restarts we have a dynamic DNS.

MYSQL db is on another computer on same LAN... my client computer's ip can change so how can i fix it

What, exactly, do you think that the client computer IP address has anything at all to do with the server computer's IP address? You need to put the IP address of the server computer in the connection string. Your client IP address has absolutely nothing to do with anything.

By default, mysql is only listen to localhost, that could be one of the reason, another reason could be the privilege of the user account for that database is not granted remote access, refer:

I do not think so. Do remember to change the server in the connection string to the ip address of your mysql server.
