Network proxy configuration changes you make on the gateway do not appear for the services
When you change the network proxy configuration on the gateway, the services do not refresh to the latest proxy configuration, leading to failure during gateway registration.
You add network proxy settings in the gateway using vCenter Server Management Interface (VAMI). The services in the gateway are aware of any proxy configuration you add. If you later change the proxy configuration, the services might not pick up the latest configuration, resulting in connectivity issues with VMware Cloud and a subsequent gateway registration failure.
Workaround: To refresh stale proxy configurations in the services, reboot the gateway after any change you make to the proxy configuration for the gateway.
