Connection Errors

While many connection errors are related to environmental issues in the Network, such as Ports and Firewall blocking, others may be due to configuration.

  1. Log in and go to Support Documentation
  2. Click All Documents.
  3. Scroll to the product installed in the environment.
  4. Click the corresponding version to your Forcepoint install.
  5. Port lists will have the word "port" in the section. The exact location within the section may change.
  6. Examples:

Installation and Upgrade Errors

There are many failures that may happen during installation or upgrade. Some of the more common causes particularly for components on Windows machines are from Data Execution Prevent (DEP), User Account Control (UAC), and Windows Firewall.
Ensure DEP/UAC/Firewall are turned off  
  • User Access Control (UAC):
    1. Click Control Panel and search for UAC.
    2. Set to Never and reboot the server after other steps are complete.
  • Data Execution Prevention (DEP):
    1. Click Control Panel and click System.
    2. Click Advanced System Settings, click Settings (Performance), and click Data Execution Prevention.
    3. Ensure DEP is turned off. For windows components/services only, reboot the server.
  • Windows Firewall:
Click Control Panel, click Firewall and ensure Firewall is turned off.
Other common factors include: Antivirus solutions installed on the machine, read-write permissions on the account used to log onto the server, and not running programs as Administrator.
