Hi @ykh525050, I am sorry you are having trouble.

Is localhost:5678 the URL you are accessing your n8n instance under? Or are you using a different URL to open n8n in your browser? If so, you might need to set the WEBHOOK_URL environment variable described here, so Google would redirect you to the correct n8n URL after completing the OAuth2 authentication flow.
