If you're on a dev machine, maybe you're connecting to your SharePoint with a SharePoint service account such as SPFarm or the account running the app pool, resulting in being logged on as "System account".
Apps cannot be deployed with System Account... You must be logged as someone else.

  • I am using different credential other than these accounts. App is deployed and installed successfully, but getting 401 Unauthorized only when i am going to open or access it. Jan 24, 2017 at 7:29
  • What kind of authentication do you use on your Web application? Kerberos or NTLM?
