I’ve set up n8n with --tunnel and followed the Google Cloud Console guide to configure OAuth 2.0 for Google nodes like Sheets, Gmail, and Drive. However, every time I try to connect, I get errors like 404 and 408 after clicking ‘Connect with Google’. I’m not sure if I’m missing something in the setup or if there’s a known issue with self hosting. Has anyone else encountered this problem and found a solution? Any guidance would be super helpful!
Thanks for your very detailed answer mate!
