Error: Host '****' is not allowed to connect to this MySQL server

Hello,
First of all, I’m new with MySQL and have a question.
I tried to connect C# to MySQL but I got an error.

This is the important code:

        connection.ConnectionString =
        "server=censored.com;"
        + "database=censored;"
        + "uid=censored;"
        + "password=censored;";
        connection.Open ();

Error message:

My question is: What did I do wrong? And how can I fix it?

Hope that helps.

Yours sincerely,
Rutger Rauws.

P.S. I apologize for my bad english.

Access in MySQL is controlled at both a user and host level. You need to allow access explicitly for the computer you’re connecting from (or use the wildcard ‘%’ to allow all hosts) with the user you’re connecting as.
