You must have connectivity with the Carbon Black Cloud.
When you sign up for the Carbon Black Cloud service, or when someone invites you to join a service, you receive an email invitation to confirm your registration. The email contains a link and instructions that you can use to activate and set up your Carbon Black Cloud console account. If your organization already has an established instance of Carbon Black Cloud, simply log in to the console using your credentials.
If you do not receive the invitation email or need any help with the Carbon Black Cloud service, you can contact the VMware Carbon Black support team at https://www.carbonblack.com/support/. If you need any help related to vSphere, you can contact the VMware support team at https://www.vmware.com/support/contacts.html.
