Error connecting to MySql database using C # application in Visual Studio [closed]

Hello, I created the registration form and at the time I am going to save the text box items in the database the following error 'Host' DESKTOP_R70LLO is not allowed to connect to this MySql server '. By my diligence to try to solve the error and based on what I already know, I believe that the user used in the connection is not having the permission to connect. In other words, this user = root, localhost, pass = 123 that I put in appconfig is not allowed to connect. But the DELETE, INSERT and etc permission is normal.
