Hi @pravingaikwad07 - apologies for the late reply. To enable auto reconnect, see this example:

        final Mqtt5BlockingClient client2 = Mqtt5Client.builder()
                .serverHost("broker.hivemq.com")
                .automaticReconnect()
                    .initialDelay(3, TimeUnit.SECONDS)
                    .maxDelay(10, TimeUnit.SECONDS)
                    .applyAutomaticReconnect()
                .addConnectedListener(context -> System.out.println("connected " + LocalTime.now()))
                .addDisconnectedListener(context -> System.out.println("disconnected " + LocalTime.now()))
                .buildBlocking();

This example is from here.

This should answer your question. Given the age of this issue I'll close this out. If anything remains, let us know. We'd be more than happy to help out!
