body: <p>We use Azure Service Bus and Azure Web App which fills queue. They are in the same resource group. We use WindowsAzure.ServiceBus v2.6.5.</p>
  
  <p>We get this error very rarely:</p>
  
  <blockquote>
    <p>The X.509 certificate CN=servicebus.windows.net is not in the trusted people store. The X.509 certificate CN=servicebus.windows.net chain building failed. The certificate that was used has a trust chain that cannot be verified. Replace the certificate or change the certificateValidationMode. A certificate chain could not be built to a trusted root authority.</p>
