Error : Nprinting Server Engine X - The QlikView Server is reachable.

[qwebnm]

Dear QlikTech,
I have a severe issue with NPrinting resulting in report generation failures.

I tried to solve the problem by restarting the QlikView Server service on QlikView Server, but unsuccessful.

After restarting QlikView server and NP server, it worked normally.
However, we are trying to figure out the cause of this issue.
I've looked at the event logs app, security, system, but I don't think there's anything that could be a problem.
Qlik masters!
How can I determine the cause of this problem?

Can you look at the logs I sent you and tell me what the cause is?
If you need more detailed information, please let me know.

Thanks & Regards.

As you mentioned, I successfully connected to the QlikView server's app by attempting to "Open on Server" using the NP server service account through RDP connection, and the connection screen appeared as shown in the attached image.

Could this indicate that the issue is not related to the connection itself? Are there any other possible causes for the problem?

If possible, I kindly request your response.

Thank you.

Thank you for your assistance.

I am already aware of the product's support lifecycle and I am currently preparing for the upgrade process. I intend to proceed with the upgrade as soon as possible. However, I encountered these issues before the upgrade and I am currently in the process of investigating and resolving them.

I kindly request the assistance of the esteemed Qlik experts in order to resolve these issues.

Thank you.

@qwebnm 
If you haven't already done so, please start a support case.

In the meantime, please check these points.

It could be a CAL issue.

1 Suggest to manually assign a CAL to the NP service account as per Dedicated NPrinting Server & Engine Service Accoun... - Qlik Community - 1716056

Manual assignment steps can be found therein. This issue may be related to a dynamically assigned. 

2. If you have multiple QVS's, ensure the NP service account is part of each QV Administrators group on each QVS.

3. Do a file/open in server as the NP service account to ensure the NP service user has access to each QVW.  The point is that if Qlik publisher exists in your environment, the NP service account should be a distribution recipient for each QVW.

Hi @Frank_S & @qwebnm 

@qwebnm - is this ongoing issue? or was it only one off in the past. A lot of test we are asking you to do have to be done at the time when you faced the issue. If you are doing them now when everything is back to normal then there is no point. You should have done those test when you experience the problem

Judging by this conversation I think you are just trying to pinpoint what had happened back then in the past when your tasks did not work. If that issue hasn't happened since then there is no point dragging this topic for much longer. 

On the other hand if it happens again - only then perform all the tests we mentioned as only then you may be able to capture the cause.

I tried to go through all comments in this topic and it seems like never ending story and we dont even know what we are looking for. In your initial post you mentioned that after rebooting machines everything went back to normal so the question I have is if the issue is still persisting?

cheers

[qwebnm]

Thank you for your reply! Here are the answers to the points you mentioned. If possible, I would appreciate it if you could confirm them.

1. CAL has already been manually assigned to the NP service account. If it appears as shown in the picture below, does it mean that it has been manually assigned?

   

2. Yes, I belong to the administrator group. Please refer to the screenshot below.

    

3. With the NP service account, I can open files on the server.

Are there any other issues I should be aware of?

If possible, I would appreciate a guide.

Thank you, Qlik expert, for always providing assistance.

Stay healthy!

Thank you for your response.

We experienced another outage due to the same issue after that.

Once again, we had to restart the server to restore normal functionality.

As the problem persists, we would like to identify the root cause and find a resolution.

If you can provide any assistance, we would greatly appreciate it.

We are always grateful for your support.

Hi @qwebnm 

again - you have restarted the server.....

next time before you restart - please perform all the tests we mentioned here as only then you can replicate the problem and gather some information.

Fact that restart helps can be related to problems outside of the NPrinting itself (like network, domain controller, account locking out etc).
