vSphere Health Service - Internet Connectivity Check

VMware vCenter Server



The health check in Skyline Health (aka vSphere Health) for internet connectivity is yellow.


Verify if vCenter Server can access vcsa.vmware.com via HTTPS/443.

To test if HTTPS Port 443 access is enabled:
1. Connect to the vCenter Server appliance through SSH or console.
2. Test the connectivity:

# curl -v https://vcsa.vmware.com

  • A successful connection should show "Connected to vcsa.vmware.com...port 443" along with some certificate information.
Please note that the text "403 Forbidden" in the results is also expected in a successful connection. Connecting to https://vcsa.vmware.com/ requires authentication parameters that are not passed by curl. Using curl to test connectivity will result in "403 Forbidden" but this still validates that vCenter can reach https://vcsa.vmware.com/
  • If result is an "error" message, then HTTPS port 443 access is likely not enabled.

Note: If your vCenter cannot directly communicate with the internet (e.g., your organization blocks the access to the internet by a firewall), you can still use vSphere Health Service as it is not required for the service to function.

If needed, you can configure vCenter  to communicate via an HTTP proxy by following the steps described in this article. Likewise, make sure that Skyline has proxy settings configured:

  1. Click Configuration.
  2. Click Proxy.
  3. Click Add Proxy.
  4. Enter the Proxy Server IP Address.
  5. Enter the Proxy Server Port.
  6. If needed, enter the Proxy Server username.
  7. If needed, enter the Proxy Server password for the user name specified in the previous step.
  8. Click Add Proxy Configuration.
