So, it's more a problem of clustering than HA (HA exemple instructions are here: https://github.com/vert-x3/vertx-examples/tree/master/core-examples#high-availability).

Can you set the hazelcast logging to INFO so we get more information. By default it uses multicast, so maybe multicast is not working in your case, or you have several network interfaces and it does not pick the right one.

To set the log level to INFO, create a logging.properties file like this one: https://github.com/vert-x3/vertx-openshift-cartridge/blob/master/usr/shared/conf/logging.properties and add it to your classpath. Edit the com.hazelcast.level=SEVERE line to com.hazelcast.level=INFO`.
