OAU-255 Access prohibited for private application

Hi I am trying to do some local testing by using the sandbox credentials from my registered application, but I am getting the OAU-255 error. This application is currently in production, can I not use the sandbox credentials to send a message?

There is a known issue with the sandbox authentication right now. 

The quick workaround solution is to change the app access type from “Private” to “Public” and regenerate a new JWT token for that app (use the app client id). 

Try that and let me know if you still face the issue.
