<p>Finally, I found the reason and resolved it. </p>
<p>Here are the steps so that other may get help:</p>
<p>1. In my event viewer, I was seeing following error: "There was an error connecting to "amqp-0-9://localhost:5672" for the RabbitMQ channel for topic "AruWorkflows": Connection failed"</p>
<p>2. It was trying to connect to localhost while I do not have rabbitmq on my local machine.</p>

<p>3. This error was coming because Neuron and RabbitMq are on same dev machine and in Neuron, rabbitmq was configured with server name "localhost". I changed "localhost" in Neuron server to IP of dev machine and it started working fine.</p>
<p>4. Looks like there is some issue with Neuron code, It should not try to connect to RabbitMq directly from client. Publisher/client is communicating with Neuron and Neuron should communicate with RabbitMq.</p>

<p>Yes, I am trying to publish from some other machine which is in same domain. When I try to publish from machine where once I installed trial version but now its expired. This machine is also different than actual Neuron dev machine. But on the other machine (where expired trial version was there), its working fine.</p>

<p>Can you tell us what build of Neuron ESB you are running?</p>
<p></p>
<p>Also, you post suggests you are using the client API to publish a message from a remote machine. Is that true? if so, can you provide us the list of our assemblies that you have deployed to the remote machine?</p>
