The error message 'FATAL: password authentication failed for user xxx' indicates a problem during the user authentication process. The most common causes include:

  • Incorrect Password: The password supplied for the user is wrong.

  • Non-Existent User: The user account you are trying to connect with does not exist.

  • Authentication Method: The pg_hba.conf file, which controls authentication, has an incorrect method specified for the user's IP address or connection type.

  • Connectivity Issues: The client cannot reach the PostgreSQL server due to network problems, such as a firewall blocking the port or an incorrect server address.
