Shield is blocking marvel

Hi Team,
I disabled shield from all nodes but when trying to access marvel (Kibana console) i am getting below error:
"Shield: Sorry, you are not authorized to access Marvel"

shield disabled as " shield.enabled: false" in elasticsearch.yml

Please let me know how can i troubleshoot this error, not sure error is on a single node or all nodes.

The only error i can found in ES logs is:

[2017-01-09 09:34:13,263][ERROR][marvel.agent ] [es-master-node] background thread had an uncaught exception
