Hi
I'm having issues with connections in NPrinting when trying to connect to all Qlik Sense apps (All connections to Qlikview are working fine)
When I run the verification check on the connection, Everything appears to be ok
But the connection always fails with "Cache Generation Failed. NPrinting Engine Failed to Open Document"
This is the log file from the NPrinting server
I've also tried recreating the connection but still get the same error. I have previously connected to this app from NPrinting so dont believe the issue is related to unsupported chart objects in the app.
Qlik Sense version is May 2022 Patch 3
Nprinting is version May 2022 (Version: 22.15.2.0)
I can also log onto the NPrinting server and open the Qlik Sense apps via a browser.
What am I missing?
At this stage I would suggest to ensure that NPrinting service account is a root admin in Qlik sense and that Qlik Sense certificates are re-issued and re-installed: https://help.qlik.com/en-US/nprinting/May2022/Content/NPrinting/DeployingQVNprinting/NPrinting-with-...

Hi Lech
Thanks for the reply. The app I used as an example didnt have any section access.
To be on the safe side, I've created new app with a single table in it with 94 rows of data
(I've blurred out the Proxy Address and Identity but happy to show these offline if needed)
I'm seeing this message on the 'View Connections' screen (Connection failed on some NPrinting Engines)
(We only have a single Nprinting Engine)
And get this error when viewing the tasks (Same as previous)
Feels like some kind of authentication issue but dont understand why the verification checks are all green ticked/successful if this is the case. I'm also able to use the user account that I'm using in the connection to log on manually onto Qlik Sense
Interesting - just wanted to confirm few more things:
Hi,
I would like to add to @Lech_Miszkiewicz 's list the suggestion to check that the Engine is correctly configured in Qlik NPrinting Web Console Admin setting and it is green online status.
Best Regards,
Ruggero
Hi Lech
Thanks
Very strange. Did you tried to create a connection to another Qlik Sense app?
Yes Indeed. I created a Test App and Test Connection in NP to the Qlik Sense app I mentoned in my previous reply (see point 5)
At this stage I would suggest to ensure that NPrinting service account is a root admin in Qlik sense and that Qlik Sense certificates are re-issued and re-installed: https://help.qlik.com/en-US/nprinting/May2022/Content/NPrinting/DeployingQVNprinting/NPrinting-with-...

Hi Lech
I've re-issued the certificates and re-installed on the NP Server and this seems to have resolved the issue. Many thanks for your help 😀 (and to @Ruggero_Piccoli )
