How to connect to Leaf nodes

How shall we connect to memsql Leaf nodes as a user, while i try to connect i get following error :
When I try to connect to leaf nodes I get Access denied for user ‘MEDICUBE_ETL_PROD_BATCHID’@‘10.203.228.122’ (using password: YES) is there as special setting require ?
My user has following grants :

How exactly did you connect to the leaf node, and why did you need to do that?
