[Sunil Patra]

Hi,

I am trying to set up Hazelcast management center.

THe UI is up and running and i am trying to set up cluster by providing yml file like below

hazelcast-client:
  cluster-name: dev
  network:
    cluster-members:
      - 192.168.0.169:5701

On the other side my hazelcast application iclient s running .(able to put and get data from cach)

But when i am launhing the cluster from management cluster, I am getting error like:

An error occurred when trying to connect to the cluster named dev. Please check that the cluster is running and the settings within the Cluster Config.

And on the application client console, i am keep on getting error like:
