recently upgraded my splunk HF with Splunk enterprise 9.1 version. Also upgraded Splunk TA add-on for New Relic.
Privious TA version 2.1.0
New TA version 2.1.6
after the upgrade TA is not able to make api call to new relic and failing with error invalid api key.
I confirmed the api key is correct and I am able to call it feom other client.
