NiFi getTwitter : HTTP/1.1 401 Authorization Required

[#1]

NiFi processor - GetTwitter with correct twitter credentials (Consumer Key, Consumer secret, Access token, Access token secret) is not working. Throws error : Received error HTTP_ERROR: HTTP/1.1 401 Authorization Required. Will attempt to reconnect.

It used to work fine for me in different environments. I have checked with network team on port blocks earlier and resolved Failed to establish Connection error. I tried multiple times of regenerating keys and updating the processor but still same error. Please advice.

Worked fine.
