Why Am I Receiving a 403 Error When Trying to Connect Multiple Email Accounts to a Gmail Developer App?

I’m trying to connect a Gmail Developer app and it’s throwing a 403 error when trying to connect it.
I’ve connected one email account successfully, but our business gets emails on several different accounts that we need to monitor.
Given that I’ve connected one successfully already, I’m assuming the config is fine and not sure if it’s a Google permissions error, Pipedream API failing, ?

Hi , I believe if Pipedream fails then you won’t be able to use any account at all.

Would you mind sharing the screenshot of the error you received?

Just to be sure, would you mind following the detailed instructions here again?

Where are you getting the 403? Can you share a screenshot?

This is the text of the error message (not sure what’s potentially confidential so I’ve redacted a few things).

Error 403: access_denied
Request details: access_type=offline response_type=code redirect_uri=https://api.pipedream.com/connect/oauth/oa_REDACTED/callback state=REDACTED prompt=consent client_id=[REDACTED-REDACTED.apps.googleusercontent.com](http://REDACTED-REDACTED.apps.googleusercontent.com) scope=https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/gmail.readonly https://www.googleapis.com/auth/gmail.modify https://www.googleapis.com/auth/gmail.labels openid

This is what’s displayed in the UI, not console logs etc

Here’s what I’m seeing when I ask Google about that error: Troubleshoot Sign in with Google - Google Account Help
