**Description**  
When our users attempt to connect to Zoom they receive the following error:

{“status”:false,“errorCode”:4700,“errorMessage”:“Empty scope (the client doesn’t have any Scope)”,“result”:null}

This happens before the Zoom sign-in UI appears indicating some issue with our app configuration. We verified in the developer portal that the scopes are still set as they should be (nothing on the app config has changed since we originally had it reviewed and published in the marketplace.

Hey @Appspace,

Thanks for reaching out about this—it sounds like this is not the case, but can you confirm you haven’t made any updates or added any additional whitelist/redirect urls to your app recently?

In order for us to take a closer look, can you share the following with us by opening up a request [here](https://devsupport.zoom.us):

- Email address of the OAuth App owner
- Example user who sees this error (email)

Thanks,  
Will
