<p>Why my pod is trying to communicate to port 8080. How to resolve this issue?
I have added the <strong>service-label-name</strong> and <strong>service-label-value</strong> property but, still I didn't get any success.</p>
<p>Is there any problem with my configuration?</p>

<p>Please set <code>service-port</code> to <code>5701</code> in order to avoid Hazelcast communicating with <code>8080</code>.</p>
