cannot verify connection; setting up Nprinting

daveatkins — Wed, 25 Sep 2019 18:40:54 GMT

I am setting up nprinting server. I go to create a connection but when I "run verification" it says:

X Engine: myservername

v Initializing..
X The connection parameters are formally valid.
v Completed

This happens for both Local and Server connections.

The engine is listed as online under admin/engine manager

I am able to open qvw from desktop software and verified the service account user has a named CAL (product launches without the personal edition label)

windows services are all running

I have tried with and without authentication for server type

I do not see anything useful in the log files; they are not actually updating based on these clicks, but are otherwise updated

myservername is the same machine as local

Hi David - did you install QlikNPrinting by yourself, What version of QlikView are you usingd?

NPrinting has to be installed and configured strictly according to all requirement in help document:

https://help.qlik.com/en-US/nprinting/June2017/Content/DeployingQVNprinting/Qlik-NPrinting-installation.htm‌

https://help.qlik.com/en-US/nprinting/June2017/Content/GettingStarted/HowCreateConnections/Create-Connections.htm

Among other requirements the main once you have to remember are:

NPrinting service account has to be different than Qlik service account
NPrinting service account has to be local administrator on QlikView server and for Server connection it also belong to QlikView administrator group on Qlik server
Needs to have UserCal license assigned if used with QlikVIew
Needs to be able to localy open an instance of QlikVIew document and save it - double check it!
Needs to have an access to qvw files
QlikView server and QlikView desktop versions should be the same
What version of QlikView are you using? are you sure it is supported? https://help.qlik.com/en-US/nprinting/June2017/Content/DeployingQVNprinting/System-requirements_engine.htm‌
To create qvp connection follow those steps: (steps included in this thread How to connect Qlik N printing 17.4 to Qlik View server)

NPrinting is not going to work if one of requirements is not met. It may seem to work then but it will be unstable!

cheers

Lech

I set up the server following those instructions. Looking at your list of requirements, I think I'm all OK except

NPrinting service account has to be different than Qlik service account

Why? I am standardizing all QlikView, QlikSense, and NPrinting to use the same service account.

Using QlikView 12; desktop and server. I installed the desktop application on the nprinting server to verify/obtain the user CAL for the service account...which I am logged in as, doing all the install, etc. The QlikView Server is:

Server System Info
	Operating System	Windows Server 2012 R2 Standard (64 bit edition)
	Operating System Version	6.2.9200
	Wow64 mode	Not using Wow64
	QlikTech Product	QlikViewServer 64-bit Edition (x64)
	Product Version	12.0.20300.0

Why different account- because it is one of the requirements listed in help documents..

Is it just a matter of changing the installed services to run under a different account or would I need to re-install?

That requirement is not listed anywhere I could find on this page, but I will try it

Hi David, just as follow up:

https://help.qlik.com/en-US/nprinting/June2017/Content/DeployingQVNprinting/User-accounts.htm

Re: cannot verify connection; setting up Nprinting

Lech_Miszkiewicz — Mon, 24 Jul 2017 02:20:45 GMT

The Windows user account must:

Be a member of the local Windows Administrators group.
Be a domain user.
Have Log on as a service rights.
Only be used to run Qlik NPrinting 17 and newer services. This ensures that there are no conflicts with other Windowsservices on the same computer.

I need to add to this my own experience - I had issues before with Qlik NPrinting 17 and i was logging qlik support cases. All of those cases were related to wrong setup or me not following setup requirements. When we were troubleshooting with qlik support the first question always was whether my NPrinting user account is different than QVS service account!

Thanks; that is helpful. They could stand to improve their documentation. I read what you cited and I did not interpret it to mean there was any problem with the service account user running QVS on a different computer, only that it had to be consistent on the nprinting server. I wonder if we will run into this problem with our QlikSense install? There are far too many user accounts involved.
