Hi @Frank_S @Ruggero_Piccoli @Gianluca_Perin
This time I am facing error which I am unable to resolve. I am helping my friends to setup and configure their NPrinting environment. Environment description:
- Single Domain
- Qlik Sense server (Qlik Sense November 2023) running on Windows 2022 Server Datacentre
- NPrinting server (NPrinting Feb 2024 SR2 - there was no lable for that version)
- NPrinting Server and Engine is installed on single machine
I guided them step by step with everything while watching and instructing them via teams regarding all steps and configuration. Now we have issue when trying to create connection to Qlik Sense app. When running validation we get error (red cross) on "Installed Nprinting certificates are not valid to connect to Qlik Sense" check.
The app we are trying to connect to is a simple app with Ctrl+0+0 script and single straight table chart - created only for testing, but in fact NPrinting is not even able to read the app since it has connectivity issue due to this certificate problem.
As far as I can tell we have everything done by the book and all other environments I have setup worked without issues in the past.
We have added NPrinting engine service account to root admins in Qlik Sense. That service account is a domain account belonging to the same domain as Qlik Sense and NPrinting.
NPrinting February 2024 SR2 is installed and activated on dedicated server running on:
- Edition Windows Server 2022 Datacenter
- Version 21H2
- Installed on 05.07.2024
- OS build 20348.2582
NPrinting Engine is active and Online.
NPrinitng is installed on server in domain "xxx.local". That is the same domain which Qlik Sense runs in. It runs on domain account which meets all requirements from:
We have verified all requirements for server and engine:
We have enabled TLS 1.2 on Qlik Sense and NPrinting servers. We have checked and verified with "telnet" that port communication is opened on 443,4242,4243 and 4747 to Qlik Sense. We also checked required cipher suits as per https://help.qlik.com/en-US/nprinting/February2024/Content/NPrinting/DeployingQVNprinting/TLS-cipher....
We have followed all steps required to export Qlik Sense certificates and installed them on NPritning machine. We paid close attention to the hostname required when exporting certificates. We have tried doing this multiple times. Also we checked that the certificate file was "Unlocked" on the NPrintign server
We have disabled "Apply Qlik Sense server certificate validation" in ADMIN-->SETTINGS-->TASK--> checkbox "Apply Qlik Sense server certificate validation". We did that few times (enabled/disabled) to make sure it didnt stall.
We also tried following below steps: https://help.qlik.com/en-US/nprinting/February2024/Content/NPrinting/Troubleshooting/NP-wont-read-QS...
We have reviewed also this post: https://community.qlik.com/t5/Qlik-NPrinting/Installed-Nprinting-certificates-are-not-valid-to-conne... and follow all steps from there with no success.
It is first time ever I am facing this issue when installing and configuring NPrinting and I cannot see anything else to check with support articles,help site or community regarding this problem.
My collegues opened support case regarding this (Qlik Support Team Your case number is : 00294396) so if there is any confidential information required I will be happy to provide it there. That case includes also logs.
I wonder what I missed - hope you guys can help.
cheers
