php artisan migrate - SQLSTATE[HY000] [1045] Access denied for user 'laravel'@'localhost'

This error message is indicating that the PHP script, "artisan," is attempting to run a database migration command, but the database server is denying access to the user "laravel" on the "localhost" location. The error message "SQLSTATE[HY000] [1045] Access denied for user 'laravel'@'localhost'" is a common error that occurs when the database server is denying access to a specific user.

This error message can be caused by a number of reasons, such as:

• Incorrect login credentials (username, password) for the database.
• The user "laravel" does not have the appropriate permissions to access the database, check if the user has the correct grant permissions.
• The user "laravel" doesn't exist on the database server, check the user exists on the database.
• Firewall issue, check if the database server is blocking connections from the script location.

It's recommended to check the database server log files for more information about the error and also check your database connection settings in the config/database.php file in your Laravel app.
