I guess in your config you are using client SSL. You defined 'secureClientPort', but no regular 'clientPort'. I think we missed to test the admin API for this case... I will create a Jira issue and try to fix it soon. Thanks for your time on testing ZooKeeper and reporting the problem! :) Mate On Wed, Nov 27, 2019 at 8:56 PM Mike Smotritsky <mikesmotrit...@ongov.net> wrote: > Hi, I've installed 3.5.5 and 3.5.6 3-server cluster.
