hi, 

do you meet all requirements from https://help.qlik.com? 

You must meet ALL of them!

Here is also link to troubleshooting messages:

https://help.qlik.com/en-US/nprinting/April2020/Content/NPrinting/Troubleshooting/Verify-connection-...

[ieshanc]

Yes all the green ticks when clicking verify, except 1 cross, QlikView Server is reachable. All the pre-requirements and guides have been considered. IC

[Lech_Miszkiewicz]

Ok i see,

I still think there is something missing from requirements:

• do you have any firewall/ports blocked between QlikView and NPrinting? (check also windows firewall)
• is your NPrinting engine service account part of "QlikView Administrators" group on QlikView server?
• can you try and do what Daniel suggested here: by going to NPrinting server as a service account, opening QlikView desktop and trying to open QVP connection to document you want to use in NPrinting - are you able to do so?
  • https://community.qlik.com/t5/Qlik-NPrinting-Discussions/Error-with-new-qlikview-server-connection/t...
• Information provided in logs suggest issues with authentication  - that suggest that there is some sort of issue with engine service account setup...

If none of the above is relevant to your case i suggest you open support ticket. 

thanks

Yes that's been done.

1 issue not sure if it's the case:

- We can't open the server using svc account due to securitym, however domain for QV & NP sever is same with QV a standalone box.

2 scenarios:

First, Run as different User --> NP svc account --> Alternate identity

            Status: Connected and opening QVW

Second, Run as different User --> NP svc account --> Windows NT (Not sure when running as diff user should make it work as NT user)

            Status: Failing with attached error

Replicated the same from my local QV desktop and getting connected with Windows NT and path as below for both local and Second test performed:

qvp://servername/ -->Picked directly from QMC-->QVS

Hi,

I think you confused both. If you cannot RDP to server as service account you can still run QV.exe as a service account.

• Navigate to your QV.exe (or simply QlikView shortcut),
• then ctrl+shif+rightclick ->run as different user.
  • 
• It will prompt you to provide domain user name and password. 
  • Provide domain NPrinting engine service account and password.
• This should open QlikView as NPrinting service account.
• From there just try to "Open in server" and |"Use NT Identity"
  • Since your QV.exe will run as nprinting account using NT identiny will also use it
• If you can successfully open qlikview application you want to use in NPrinitng then great, but if you dont then you first need to meet requirements for service user accounts
