NPrinting Connection fails to generate metadata

[QlikToFindOut]

Hello,

I just finished a fresh install of Qlik NPrinting May 2021 SR2 and am looking to connect to Qlik Sense which is also on May 2021 (Patch 4).

When verifying the connection, I get all green checkmarks, but when it comes time to generating the Qlik metadata, it just times out with no intelligent error message:

November 24, 2021 11:32:58 AM	Info	Execution reset by scheduler startup
November 24, 2021 11:33:08 AM	Info	Execution reset by scheduler startup
November 24, 2021 11:33:18 AM	Info	Execution reset by scheduler startup
November 24, 2021 11:33:28 AM	Warn	Exceeded maximum number of retries

When I check the NPrinting log files, I do see this:

20211124T113220.167-05:00 [39] INFO Engine.Navigator.QlikSense.SDK.Rendering.SenseAuthenticator - Engine.Navigator.QlikSense.SDK 21.14.5.0 Engine.Navigator.QlikSense.SDK.Rendering.SenseAuthenticator 20211124T113220.166-05:00 INFO MYNPRINTINGSERVER1 0 0 0 0 0 0 0 0 trying to get login cookie via a qlikTicket from: https://MYQLIKSENSESERVER1.fss.anitech.com/hub/?qlikTicket=CLjdwBN92wWXWzwJ

And then right above it, I see:

20211124T110319.461-05:00 [26] ERROR Engine.Navigator.QlikSense.SDK.Rendering.SenseAuthenticator - Engine.Navigator.QlikSense.SDK 21.14.5.0 Engine.Navigator.QlikSense.SDK.Rendering.SenseAuthenticator 20211124T110319.461-05:00 ERROR MYNPRINTINGSERVER1 0 0 0 0 0 0 0 0 An issue occurred in MashupServer.GetAuthenticationCookiesAndConsumeQlikTicket.

Aside from generating the certificate from the Central node and copying it over to the NPrinting server, are there any other steps I need to take to get past this? The NPrinting metadata generation only fails because it seems like it's just simply timing out. Not sure where else to be looking. For background information, we also have three rim nodes which are used as load balancing engines, but I don't think I need to generate anything from them.

Thanks for your time!

@svuradi - Your answer is an example of why it is so important to have version of NPrinting provided with the question. Your answer applies to very recent versions (2023) as from that time the setting you are talking about was introduced, however it is invalid and does not apply when talking about May 2021 version from question and in fact may confuse users who are not aware of this difference.
