If the attempt to replace the self-signed certificates with custom certificates fails, an administrator must revert to the self-signed certificate.


  • Verify that you have root user credentials for the VMware Skyline Health Diagnostics appliance.

  • For more information about enabling the root user log in to the VMware Photon OS, see: https://vmware.github.io/Photon/assets/files/html/3.0/Photon_troubleshoot/permitting-root-login-with-ssh.html (This configuration is not necessary for the VMware Skyline Health Diagnostics appliance as by default it is configured to allow root user log in through SSH).

  • Verify that you can log in using root credentials to the VMware Skyline Health Diagnostics appliance console.


  1. Open the Skyline Health Diagnostics appliance console using the VMware vSphere client or Secure Shell (SSH) client.
  2. Log in as root user.
  3. Run the command shd-config refreshcert.


The VMware Skyline Health Diagnostic appliance services starts using the refreshed self-signed certificate.
