  • When editing a backup job with vSphere Data Protection (VDP) 5.5.1 or when viewing the Configuration tab of the VDP appliance, you see the error:

    Failed to acquire all licenses 

  • When acknowledging the popup, the VDP UI times out and does not allow you to edit the backup job. 
  • The VDP Advanced license assignment section of the Configuration tab fails to populate with data.
  • In the /usr/local/avamar/var/vdr/server_logs//vdr-server.log file, of the VDP appliance, you see entries similar to:
    ERROR [http-nio-8543-exec-1]-rest.LicenseService: Failed To Get All License Keys
    java.rmi.RemoteException: VI SDK invoke exception: <VARIABLE MESSAGE>

    • The exception thrown can vary depending on the application that is listening on port 80.
    • The exception <VARIABLE MESSAGE> can indicate any exception, such as connection exception or IO Exception.


The VDP appliance stores VDP Advanced license information in the vCenter Server extension that is a part of the VDP plug-in. When performing certain actions, such as editing a backup job, the VDP plugin checks for the VDP Advanced licenses. This check is performed by accessing https://sdkTunnel:8089/sdk via http://vcenter-ip:80 as the proxy.
This issue occurs if vCenter Server is configured to use a port other than 80 for HTTP.


This is a known issue affecting VDP 5.5.1.

To work around this issue:
  1. Verify port 80 on vCenter Server is open and is not blocked by firewall.

    For more information, see:

  2. Disable any other application that is listening on port 80 or reroute it to use a different port.
  3. Verify and ensure that vCenter Server is currently using port 80 for HTTP.

    To verify if vCenter Server is using port 80:
    1. Connect to vCenter Server using the vSphere Client.
    2. Click Administration.
    3. Click vCenter Server Settings.
    4. Click Ports.
Note: To modify the HTTP port number, you must reinstall vCenter Server and keep the default port (80) during the installation.
For more information, see:

Additional Information

  • vCenter Server requires port 80 for direct HTTP connections. Port 80 redirects requests to HTTPS port 443. This redirection is useful if you accidentally use http://server instead of https://server. If you use a custom Microsoft SQL database (not the bundled SQL Server 2008 database) that is stored on the same host machine as the vCenter Server, port 80 is used by the SQL Reporting Service. Also, Microsoft Internet Information Services (IIS) uses port 80. For more information, see the Conflict Between vCenter Server and IIS for Port 80 section of the vSphere Upgrade guide.
  • If you are running VDP version 5.5.5, see Deploying or upgrading a VMware vSphere Data Protection appliance configured with a custom HTTP port (2062947).
