我的连接收到拒绝访问警告

I have problem with my connection. This is a shared server and I have use SSH to check my database and my tables. I use the same credential to access them thru the web. However it gives me error. I check for any typo, but they are correct and my sql access and my database don't have username or password. So I only have one user and pass for my host. I have created my tabales and uploaded my pages to the same database with same username and password.

# Can this problem be the server problem? so whoever established did not configure it correctly?? #

this is the error:

Warning: mysql_connect(): Access denied for user 'cop...'@'139.62.63....' (using password: YES) in /home/cop.../homepage/login.php on line 10 Could not connect to database

and here is my code, is there anything that I can do? can you think of anything else, but typo ?

    <title>Login</title>

<body>

if(!($sqlCon= mysql_connect("139.62.63...","cop..","abcdef")))
    die( "<p>Could not connect to database</p>" );

if (! ($dbCon = mysql_select_db("cop..", $sqlCon)))
    die( "<p>Could not open database</p>" );

Incorrect password to connect to MySQL. Check your configuration. It's funny that you are creating a login form to verify username password when in fact your application cannot connect to the database.
