title: Azure Network Performance Monitor - Issue with discovering agents
body: <p>We have requirement to allow communication between SUSE Linux based VM located in Microsoft Azure and on premise SUSE Linux based server. Also need to configure NPM to detect network issues like traffic black holing, routing errors etc.</p>
  
  <p>Steps:
  We have configured NPM based on steps mentioned in below link. (also opened TCP in bound and out bound port 8084 for Azure SUSE Linux based VM).</p>

  <p>Issue: As seen in screenshot 1, NPM workspace shows that 2 VM’s are connected (i.e. On premise and Azure VM’s) . 
  However when “Discover Express Route Resources” is clicked, it doesn’t show any nodes. See screenshot 2 for reference. Even if you click on “Add Azure Agents”, there is no agent/node discovered.</p>
  
  <p>Are we missing anything here?</p>
