NPrinting June 20 upgrade failure - Verification error QlikView Server is reachable -shows as fail

[paul_ripley]

I have been using a consultant to help me upgrade QV to April 20 and NPrinting to June 20.  QV upgrade was fine but the NPrinting I am having issues with.

Firstly I cannot reload meta data on the Connections..The task error shows

Cache generation failed: NPrinting Engine(s) failed to open document: navigator=qlikview;documentpath="qvp://DCL1-QLIK-WV03/FIN-LIVE-UserApps/Board report/BoardReport.qvw";identity=3i\serv-qlikview. Check connection page for connection status.. Check logs for details

But I can open the report from N Printing as 3i\serv-qlikview

In Connections when I run verification

 The QlikView Server is reachable. - this shows as fail

Do you know what I could check?  Thanks

Paul

In the scheduler log file:

Connection navigator=qlikview;documentpath=qvp://DCL1-QLIK-WV03/FIN-LIVE-UserApps/Costc/Cost_Report.qvw;identity=3i\serv-qlikview recorded an error in startup

Hi Paul

Please note that we are currently working on this 'authentication failed' issue with another customer via a ticket submitted to our support desk.

The investigation ID is OP-9493 for your reference purposes. 

Please start a support request with the Qlik Support desk and quote the above ID so that you can add your voice to this issue.

Thank you.

[Frank_S]

@paul_ripley 

Also if possible and when convenient, please modify this discussion title so that it more accurately represents the specific issue with regard to the verification error that you are seeing.

[Lech_Miszkiewicz]

Hi @paul_ripley 

I see 2 issues here: 

1. First -  You say you have upgraded to QV April 2020 - as per documentation this version is not supported. @Frank_S - would that be your comment too? https://help.qlik.com/en-US/nprinting/June2020/Content/NPrinting/DeployingQVNprinting/System-require...

2. Second - You said you have upgraded QlikView to v April 20. Based on your logs your QV desktop is still November 2018. Did you forget to upgrade QlikView desktop on the nprinting engine node?

thanks L.

[Frank_S]

Yes @Lech_Miszkiewicz I do agree with your 'unsupported' comment. 

We are, however, seeing this issue in supported versions of QlikView desktop and server as well with June 2020 and later. Thus far this is an 'edge' case (only 2 reported including this one) that we are in the process of investigating.

[Lech_Miszkiewicz]

Thanks @Frank_S  - good to know!

[paul_ripley]

The customer you are dealing with is possibly the consultant I was using as he said he had logged a ticket with Qlik.

As per Lech it is possible that the issue is that we upgraded to N Print June 20 and assumed that the best thing to do was also to upgrade to April 20 QV but the documentation says April 20 QV is not supported by N Printing June 20

[paul_ripley]

1.) So it appears we need to roll back to April 2019 for QV and for N Printing? Would that be the suggestion as the latest version of N Print doesnt work with the latest version of QV?

2) I checked and not sure why the log says that as the QV version on the N Print server says April 20

[paul_ripley]

So just to double check, the best thing to do is roll back to April 2019 for QV and N Printing?

[Frank_S]

@paul_ripley 

Please open a support case if you haven't already done so and share this community discussion and OP-9493.

It is a theory only, at this stage of the investigation, that the problem is in NP June 2020. 

Rolling back may or may not be the solution. If you have a test environment that you can work with, that would be ideal and test an older version of NPrinting there.

For PROD, I would suggest switching to local connections and scheduling regular NP connection reloads until we can solve the issue on our end.
