OAuth Resource_access_error

[LakZoom]

I have been trying integrate zoom with my own app. Its a general app. I have given all the details like redirect_uri, client_id and client_secret . when I try to connect the connectors or  preview my app listing it throws resource_access_error. What does it mean and How do I fix that.
