I installed N8N, and when I created a Facebook Lead Ads Trigger and created a new credential, I got this link: https://0.0.0.0:5678/rest/oauth2-credential/callback

Here:

OAuth Redirect URL

When I put that same thing in the Google app it gives me an error because obviously it doesn't find anything like that.

It tells me this when connecting everything correctly:

Can't access this site

It is possible that the web page in https://0.0.0.0:5678/rest/oauth2-credential/callback?code=AQD0WpgFaKZQLcSVlrXNxVBXpMXsOS-kr0pWrNkxRnX-eX42iQIJIrvMG22AyVFgpOE6nfrjmA7eiAje9exfUSdgf
