Solutions

1. Verify the Brunt account username and password are still valid and reconfigure the integration with correct credentials.
2. Log in to the Brunt app to confirm the account is not locked or the password changed.
3. Re-authenticate via the integration's reauth flow when prompted.

Example fix

The Brunt API returned HTTP 403, meaning the stored credentials are rejected. Reauthenticate with a valid Brunt account username and password via the config entry's reauth flow.
