It is possible that the Cyren engines used generate error messages that are not traceable to the engines themselves, but to communication problems with Cyren data centers. This article shows you ways to test the communication and function.

Troubleshooting

In the following section you will find a small checklist, which you should always check before the first request to the support

  • Is the necessary module licensed in NoSpamProxy? If not, you don’t need the services and can disable them on the system in the Windows services.
  • Has the Knowledge Base article How to configure on-access virus scanners been applied to all systems with the appropriate services?
  • Is a web proxy required for Internet communication in your company and is it registered according to the knowledge base article How to configure CYREN services?
    • This must be checked and re-entered after each NoSpamProxy Update/Upgrade.
    • Always edit the newly created file, never overwrite it with an old version of the file.
  • Is it possible to communicate with and/or without web proxy to all mentioned external systems of Cyren?
  • Are there any exceptions on the firewall to access all sub-domains from ctmail.com? These connections must not be used for virus scanning, content filtering, or other checks!
  • Are there any error messages when the services are running interactively via the command prompt (CMD)? To run interactively, please follow these steps aus and attach a screenshot of the request’s communication to support.
    1. Stop each service from Microsoft Windows services.
    2. Open a prompt with administrator privileges.
    3. Run the command for the service, to be tested. Use the path to the corresponding executable if you do not have NoSpamProxy installed in the default directory
      • Ctasd
        CMD > “C:\Program Files\Net at Work Mail Gateway\Cyren Integration Service\ctasd.exe” -c “C:\ProgramData\Net at Work Mail Gateway\Cyren-ctasd.conf” -i
      • Ctipd
        CMD > “C:\Program Files\Net at Work Mail Gateway\Cyren Integration Service\ctipd.exe” -c “C:\ProgramData\Net at Work Mail Gateway\Cyren-ctipd.conf” -i
      • Ctwsd
        CMD > “C:\Program Files”Net at Work Mail Gateway\Cyren Integration Service\ctwsd.exe” -c “C:\ProgramData\Net at Work Mail Gateway\Cyren-ctwsd.conf” -i
    4. Copy the output or take a screenshot of the output.
