title: How to access Camunda Cloud from inside corporate network
body: <p>I’m building a PoC with Zeebe</p>
  <p>I was able to run from my local pc the Java client at <a href="https://github.com/camunda-cloud/camunda-cloud-get-started" rel="nofollow noreferrer">https://github.com/camunda-cloud/camunda-cloud-get-started</a></p>
  <p>Now, when I try to run it from my corporate PC, I’m getting the error below. I understand that I need to fix some network configuration to make it work. Is this configuration documented anywhere?</p>
  <p>Many thanks.</p>
