Can’t sign In after adding client/secret keys for Youtube
I add the keys (they are corrent), the singin button shows, I click on it and receive this:
At Google’s popup:
You can’t sign in because this app sent an invalid request. You can try again later, or contact the developer about this issue. Learn more about this error
If you are a developer of this app, see error details.
That error tends to mean that the URI in the Google App doesn’t match what n8n is set to use, I would start by double checking the redirect URI for the credential and in Google and see if it needs changing.
I noticed your setup mentions you are running n8n from the website, Based on your question I assume this isn’t cloud and maybe desktop?
Where you create your credential in n8n and add the ID and Secret there is an OAuth Redirect URL that is the value that should be put into your Google App. It should be something like https://oauth.n8n.cloud/oauth2/callback
