            <strong>The host exists, but doesn't have a matching path.</strong>
            Check if the URL path was typed correctly and that the route was created using the desired path.

          <li>
            <strong>Route and path matches, but all pods are down.</strong>
            Make sure that the resources exposed by this route (pods, services, deployment configs, etc) have at least one pod running.
