Connecting to YouTube API

I’m a newbie with API calls.
I created a Google Cloud Console project to download captions using the YouTube APIs.
Then I added a Make an OAuth 2.0 request module. It fails when I try to create the connection. I get this error

But I already added that URL to my Authorised redirect URIs

What should I do?

Hey Alberto,

which redirect URL are you using?

Its this one:

https://www.make.com/oauth/cb/youtube

Thank you.
Where do I find it?
