3 years ago You need to update your redirect URI from whatever it is to https://harlunfh.com/?google_response, on the Authorized redirect URIs section of the OAuth Client ID page on Google for it to match what it is in the application.

the redirect URI in the request, https://harlunfh.com/?google_response, does not match the ones authorized for the OAuth client. To update the authorized redirect URIs, visit: https://console.developers.google.com/apis/credentials/oauthclient/${your_client_id}?project=${your_project_number}
