New Connection not getting created rabbitmq java client

Question

I've just started studying rabbitmq. So while just doing some basic stuff in rabbitmq with java client am getting the below issue

Exception in thread "main" java.util.concurrent.TimeoutException
    at com.rabbitmq.utility.BlockingCell.get(BlockingCell.java:76)
    at com.rabbitmq.utility.BlockingCell.uninterruptibleGet(BlockingCell.java:110)

    at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:930)
    at com.sharique.jobs.HelloWorldProducer.produce(HelloWorldProducer.java:32)

and below is the code to create a connection

ConnectionFactory factory = new ConnectionFactory();

                factory.setUsername("guest");
                factory.setPassword("guest");
                factory.setHost("localhost");
                factory.setPort(5672);
Connection connection = factory.newConnection();

And one more thing i.e., rabbitmq server is running.

Please help

Is there a blocking firewall ? What does telnet localhost 5672 do ? Does it get in ? — Ramachandran.A.G, Jan 29 '17 at 15:51
Not sure i get it , in the client code you are connecting to a local instance of RabbitMQ. What is this host 0.0.22.40 ? Does telnet localhost 5672 connect ? — Ramachandran.A.G, Jan 29 '17 at 15:56
I don't know exactly what actually it is... And I also checked, firewall is turned off — Sharique, Jan 29 '17 at 15:56

Sorry... Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. Am getting this response — Sharique, Jan 29 '17 at 16:18
I am pretty sure it is some kind of a network firewall or similar issue. Basically the application connects and gets terminated externally. Can you try disabling the firewall and check ? https://github.com/rabbitmq/rabbitmq-tutorials/issues/101 — Ramachandran.A.G, Jan 29 '17 at 16:20
yeah I even saw that post and I have checked it...in my local system firewall is turned off — Sharique, Jan 29 '17 at 16:29
Yes you were ryt...there was some kind of network issue and it turned out a DNS issue...its resolved. Thanks for the help — Sharique, Jan 29 '17 at 17:33

Set the virtual host setVirtualHost like:

String uri = System.getenv("URL");
if (uri == null) uri = "amqp://guest:guest@localhost";

ConnectionFactory factory = new ConnectionFactory();
factory.setUri(uri);
.
.
factory.setVirtualHost("/");
Connection connection = factory.newConnection();

You could also set setConnectionTimeout.
