  1. Login to Qlik NPrinting Server with  Service Account and open NPrinting Web Console with NPrinting Service Account.
  2. Verify that the Qlik NPrinting License service is up and running.
  3. Try to restart the Qlik NPrinting License service and try to apply for the NPrinting SLK License before going to the next step.
  4. Verify that the Qlik NPrinting server has an active internet connection and that connectivity to license.qlikcloud.com on port 443 is possible from the server running the Qlik NPrinting licensing service.  (You must get "default backend - 404" in the browser when accessed to license.qlikcloud.com)
  5. In some rare cases, the Server only has temporary access to the Internet, so sometimes it is able to connect to https://license.qlikcloud.com and sometimes not. It needs to have permanent access to the licence-URL, to be able to correctly work.
    • If you are in the above rare cases or if the sync doesn't seem to be performed, there is a way to force the sync: remove one/more characters from the SLK License and click to "apply".

      The license will be refused as it's an incorrect one. This action will force the license synchronization. Now, try to apply with an actual SLK License.

  6. If the above did not resolve the issue, check if you have a proxy configured in the NPrinting Server.
    • Open Internet Options from Control Panel and check for Proxy IP/URL



    • If the Proxy is configured, do the changes accordingly in "%Program Files%\NPrintingServer\NPrinting\License\license.configusing Licensing service proxy Setup 
    • Make sure to Stop and Start the Qlik NPrinting licensing service before and after performing the changes.



When you upgrade the Qlik Nprinting Server, the existing configurations files will be overwritten to default configurations files, and any changes done before the upgrade have to be updated again.

So make sure to take a backup of the Files (Eg: Config) and Folders before performing the upgrade.
