Hi Seye, usually, Flink's web UI should be accessible after a successful leader election. Could you share with us the cluster logs to see what's going on? Without this information it is hard to tell what's going wrong.
What you could also do is to check the ZooKeeper znode which represents the cluster id (if you are using Yarn it should be something like /flink/application_...). There you could check the contents of the leader znode of the web ui (leader/rest_server_lock). It should contain the address of the current leader if there is one.
