When the certificate of the Tunnel Service expires, you must replace it with a new self-signed or a CA-signed certificate.

Replace the certificate of the Tunnel Service only in cloud sites.

Prerequisites

Verify that you are prepared to follow the steps in these procedures when replacing the certificate:

Procedure

    1. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    2. Click Login.
  2. Log in as root.
  3. Generate or upload a new certificate.
  4. Log in to the management interface of the Cloud Replication Management Appliance.
    1. In a Web browser, go to https://Appliance-IP-Address/ui/admin.
    2. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    3. Click Login.
  5. In the left pane under Configuration, click Settings.

Without further actions, within 30 minutes VMware Cloud Director Availability negotiates the certificate and restores the connectivity.
