The scopes are all listed within the URL, and client_id is right and the domain is right but still get the error..
As part of the install on the dialer, I have to create an App in the clients Hubspot environment first, and then authorise that with an access token. As part of the real time updates, I have to then make an app in my developer account. I have to provide domain, client id, secret, app id and app api key for the app I create in the developer account. When I provide this, and click authorise, I get this error.
When I enter the Redirect URL (from the full URL you posted) I get the response: ERR_CONNECTION_TIMED_OUT
That may be the issue?
Regardless I would double check your Redirect URL on the Auth Tab in your App.
Have fun
