Answer 1

What do you mean "in cpanel?" Is your MySQL server running at a hosting provider? Is your client on your local machine? If so, that means you're trying to connect between your MySQL client and the server via the public internet. It certainly looks like this is what you're trying to do.

A lot of hosting providers don't allow this. Yours does, because the message you're getting says that the MySQL server is rejecting your particular connection request.

You need to grant access privileges in your MySQL data base so

XXXr@%

or maybe

XXXr@adsl-109-74-46-204.dynamic.yemennet.ye

can get access to your database. The first choice grants access to the user XXXr attempting to connect from any host. The second mentions the hostname that goes with your current ADSL access IP number.

If you can't figure out how to grant this user privilege (also known as user access) via your cpanel, ask you hosting provider's tech support for help.

It's possible your hosting provider -- the service that runs the MySQL server and provides cpanel access to it -- won't allow this. It's generally considered somewhat insecure to allow MySQL database connections from the public internet.
