Troubleshooting tips for CUC cont..

Problem Description

1. VMRest API throws 401 response error

Solution

1. Check if OAuth Token has expired

2. Check if OAuth Token is no longer valid

-If the Tomcat service is restarted then all previous tokens are no longer valid and the client have to request for a new token.

- If the publisher server of Unity Connection cluster went down then the token generated on the publisher server becomes invalid, and clients have to request the subscriber to generate a new token.
