Article Number: 000059277 | Last Modified: 2019/12/31
NPrinting Engine remains offline
Environments this article applies to:
November 2018 and newer versions of NPrinting
See Video for General Installation/Configuration Details.
What has changed?
A new certificate process which secures communication between the NPrinting server and the NPrinting Engine has bee added as of the November 2018 release of NPrinting and newer versions
New port exemption required: port 4997 needs to be opened outbound on Qlik NPrinting Server and inbound on all Qlik NPrinting Engines
Some RabbitMQ users are missing during the NPrinting installation
Workaround for September 2019 and earlier versions:
This article contains a video showing the steps to installing the NPrinting Server>Admin>Engine manager and the new NPrinting Engine certificate steps during the Engine Install process.
When installing the NP Engine software, ensure to carefully document the certificate password used as it will be needed again when configuring the updated Engine in the NP web console/Engine Manager interface
You will also need to insert the Engine certificate password for the Engine in Admin>Engine Manager and click Save.
Once the steps in the video below are completed, the NP Engine Status will return to 'Online'
! If the steps in the attached video are not followed, the NPrinting Engine will likely remain in an 'Offline' status after an upgrade from NPrinting versions prior to November 2018 release or later versions.
Solution which does not require uninstalling and reinstalling the NP engine and the Engine Manager engine entry
Note: to use this solution you must upgrade to November 2019 or newer releases of NPrinting
On the Web Console Engine page, you might have a Qlik NPrinting Engine that is enabled, but offline.
In this case, you need to resend the certificates.
The resend form is now automatically unlocked.
You need to complete the form with the password and resend the certificates to enable the Qlik NPrinting Engine online.
There is no need to reinstall the certificates nor the NPrinting Engine
