You have an application hosted on a Compute Engine virtual machine instance that cannot communicate with a resource outside of its subnet. When you review the flow and firewall logs, you do not see any denied traffic listed. During troubleshooting you find: "¢ Flow logs are enabled for the VPC subnet, and all firewall rules are set to log. "¢ The subnetwork logs are not excluded from Stackdriver. "¢ The instance that is hosting the application can communicate outside the subnet. "¢ Other instances within the subnet can communicate outside the subnet. "¢ The external resource initiates communication. What is the most likely cause of the missing log lines?
