This MySQL error occurs when a user tries to connect to a MySQL database and the credentials are either incorrect or the user does not have the necessary permissions to access the database. The error can appear whether the password is provided or not (indicated by the YES/NO in the message).

MySQL

Why This Error Occurs

  • Incorrect Username/Password: The username or password supplied in the connection request needs to be corrected.
  • User Permissions: The user does not have the necessary privileges to access the database from the specified host.
  • Host Mismatch: MySQL differentiates users based on the host they are connecting from. The user may be trying to connect from a host (IP or hostname) that is not allowed.
  • Password Requirement Mismatch: The user might attempt to connect without a password, but the account requires one (or vice versa).

Troubleshooting steps

1. Check Username and Password:

  • Ensure that the username and password provided are correct.

3. Ensure the Host is Correct:

  • MySQL allows users to connect from specific hosts (localhost, %, 127.0.0.1, etc.).
  • If the user is connecting from a remote host, ensure that MySQL is configured to allow access from the correct IP:

  • The % wildcard allows access from any host, but you may restrict it to specific IP addresses.

4. Check MySQL Configuration:

  • MySQL may be configured to disallow remote connections. Check the my.cnf or my.ini configuration file to ensure that bind-address is set to 0.0.0.0 or the appropriate IP to allow connections from other hosts.
  • Restart MySQL after modifying the configuration:
