Qlik NPrinting Engine Offline status

Possible cause  

The status of a Qlik NPrinting Engine is always "Offline" on the Engine manager page.

Proposed action  

Do the following:

  1. If an engine goes offline a few seconds after starting, check the nprinting_engine.log file stored on the computer. The text QlikView license violation detected means that you have to activate a QlikView Desktop license for the Windows user who runs the service.
  2. Check that the Qlik NPrinting Engine and the Qlik NPrinting scheduler service services and processes are running. A failure of the Qlik NPrinting scheduler service can cause the engine status to not be updated.
  3. If Qlik NPrinting scheduler service and Qlik NPrinting Engine are running on different computers, or if you provided a computer name or a fully qualified domain name (FQDN) to the Qlik NPrinting Engine installer (including localhost), check that port 5672 is open for inbound connections on the Qlik NPrinting scheduler service computer.
  4. If you used localhost for the computer name during the engine installation, open a command prompt (cmd.exe) and check that ping localhost works. Some DNS configurations prevent localhost from being resolved to the loopback network interface.
  5. Check that the computer name is correct on the Engine manager page. Do not use a fully qualified domain name (FQDN) or localhost.
  6. Check the engine and scheduler logs for connection errors or other failures. If failures appear in the logs, refer to their troubleshooting help to resolve the failure, then restart the services.

Possible cause  

Your engine is "Offline" and you recently did all of the following:

  • Upgraded to Qlik NPrinting September 2019 or higher, from one of the following versions:
    • November 2018
    • February 2019
    • April 2019
    • June 2019
  • Changed the services user accounts. See: User accounts

Proposed action  

Do the following:

  1. In the Qlik NPrinting web console, go to Admin > Engine manager.
  2. Remove and recreate the related engine entry.
  3. Fill out the certificate form to send the new certificates to the engine.
