**Description**  
I have an app published to the Zoom App Marketplace ([https://marketplace.zoom.us/apps/T0eEAEPAStWKZ5v-iGtgIQ](https://marketplace.zoom.us/apps/T0eEAEPAStWKZ5v-iGtgIQ)), but when a user tries to connect they get the error. It seems to be just happening for this specific user.

**Error**  
You cannot authorize the app - This app cannot be installed outside of the developer’s account. Please contact the application developer to get support with installing this application.

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
OAuth

Hey @northernbeacheswebsi,

Strange, can you private message me the affected id or email of the user so I can take a look?

Thanks,  
Tommy

This has been resolved, the user was using a Sandbox account. Sorry for the hassle.
