Environment

VMware HCX

Cause

The HCX Web UI becomes inaccessible when the app-engine and web-engine services fail to initialize properly or are delayed during the appliance startup sequence. This behavior is often triggered by consecutive HCX Manager reboots.

Resolution

To restore service immediately, follow these steps:

1. Log in to the HCX appliance command line.

2. Verify the status of the services:

systemctl status web-engine
systemctl status app-engine

3. Restart the services manually:

systemctl start web-engine
systemctl start app-engine

4. Verify the services have started successfully by checking the logs for a running state.

If the services fail to start after manual restart, contact Broadcom support and reference this article.
