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 https://service.ringcentral.com. If you can login the service web, you should be able to login your app with the same credentials.
I'm using credentials from https://developers.ringcentral.com/ under Production Environment section. This is private app.
After login from https://service.ringcentral.com I got this message.
so my app is in production now . I use live credentials as following:
RINGCENTRAL_ID=xxxxxxxxxxyBSTB7w
RINGCENTRAL_SECRET=xxxxxxxxxxxxxxxxxxxx
RINGCENTRAL_URL=https://platform.ringcentral.com
RINGCENTRAL_USERNAME="xxxxxxxxx4735"
RINGCENTRAL_PASSWORD="xxxxxxxxxxxx"
RINGCENTRAL_EXTENSION="101"
maybe i have a wrong MVP premium account linked to my app?
can you please confirm the credentials
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.
we did upgrate to MVP Premioum. I spend a week on the phone with customer support to do it.
I have submitted the live MVP premium account number twice for this app.
what else can i do?
That is your free account. Stop using this. Login developers.ringcentral.com 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.
Using the RingCentral Phone for Desktop, you can dial or receive test calls, send and receive test SMS or Fax messages in your sandbox environment.

Tip: switch to the "sandbox mode" before logging in the app:
