That is your free account. Stop using this. Login with a user under your MVP premium account (should work with the super admin user). Feel free to add more users as a developer to the dev portal.

You can submit a support ticket to get further support too.

How do you authenticate? Is the user under your production account? Trust the error message and check your user login credentials. Double check by login If you can login the service web, you should be able to login your app with the same credentials.

After login from I got this message.

That is the case. Your app is created under your free-tier sandbox account. With such an account, you can only make public apps and allow all RingCentral users using your app.

The SendFax app is a private app, and it is a password flow app, which means that you cannot login the app with any user credentials under other accounts than your own account. But as this is a free-tier account, it is not associated with your MVP premium account.

You have to login the sandbox associated with your MVP premium account, create a new app, test and graduate it. Then you can login with any user under your MVP premium account.
