@Naveen_Sagar  I am not sure if this is the right solution, but if you are using NiFI itself to communicate with its own NiFi API,  you can skip the authorization token completely as NiFi is already authorized to execute its own API calls.

@Naveen_Sagar 

The Bearer token is issued by a specific NiFi node for a specific user identity.   That Bearer token has a limited life time and can not be used to authenticate a user on any other NiFi node (even one in the same cluster as the original node that provided the bearer token). 

All rest-api endpoints will require some level of authorization.  So simply having a valid bearer token for an authenticated user identity, does not mean that user is authorized to access/interact with every rest-api endpoint.   In your case, the user would need "operate the component" or "view the component" and "modify the component" authorizations in order to change the run-status.

You should inspect the nifi-user.log on the aaa.com nifi server to see what user identity attempted to change the runs-status on that node and was not authorized.  Then verify the necessary authorization is setup for that user identity and try your curl command again.

And make sure as @ckumar pointed out that in his curl example that you are using the "-k" flag which allows curl to auto trust the serverAuth certificate presented in the TLS exchange with your secured NiFi.
