Appium fails locally- Android

Hi there,
We have a selenium grid that runs the test on Nexus 6. It works.
BUT, if I try and use the same parameters on a local Appium, I get the following error:
{“status”:33,“value”:{“message”:“A new session could not be created. (Original error: Permission to start activity denied.)”,“origValue”:“Permission to start activity denied.”},“sessionId”:null}

On Emulator I can run locally.
I saw this discussion (, but as it runs when I run it through grid, I wasn’t sure the response there is relevant to me.
