If you are experiencing registration issues, please check the following: 

• Network connectivity—The agent must be able to communicate with the vault. If networking errors or other issues interfere with this communication process, the agent will not successfully register with the vault.
• Previous Installations—The Direct-to-Cloud agent cannot currently be installed over an existing agent. If an agent has been previously installed, it must be uninstalled. You must also delete the existing agent folder.
• 
• Failure to remove the previous agent files will prevent the Direct-to-Cloud agent from registering with the vault.
• Firewall considerations—The agent needs to communicate outbound on the internet to the vault on the following ports:  443, 9079, 9082, and 9090.
