On Demand Button

Tool_Tip — Sun, 23 Jun 2024 07:19:17 GMT

Dear all,

N-Printing reports are not visible on clicking "On demand" button :

I have followed all the steps from below post:

https://community.qlik.com/t5/Qlik-NPrinting/QS-On-Demand-Reporting-control-keeps-prompting-me-for/td-p/1950487

I have added Qlik sense server as trusted origin in nprinting admin.

Hi @Tool_Tip

As always before attempting to do anything we need to make sure we understand all requirements which are here:

So just to sum up:

make sure both your NPrinting and Qlik Sense are in the same domain
- like https://QlikSense.tooltip.com
- like https://NPrinitng.tooltip.com:4993
make sure you have SSL certificate installed and configured for both sides with FQDN
make sure you whitelist those in TrustedOrigins as documented in earlier mentioned links
make sure you use FQDN (Fully quialified domain names) when configuring your ondemand control
make sure you have OnDemand enabled on reports
make sure you have role assigned to user which allows for OnDemand report generation

Once you meet all those basic requirements it will work sweet as charm.

Lastly - if you still have issues watch youtube video about it: https://www.youtube.com/watch?v=eHVBVoLy16Y

Dear Lech,

Thank you for you response as all the time.

Yes. I make sure to follow every steps given. Also I want to try with this

"make sure you have SSL certificate installed and configured for both sides with FQDN"

What I can see now is qliksense server certificates are installed on nprinting server but I want to confirm if I need to installed nprinting certificates in qliksense server too? if so, how I can export the nprinting certificate and which one either root, client or server .pfx or all of them?

Let me give try this option...

Hi @Tool_Tip

I think you are talking about different ceritficates and those are not the once we need.

Those which have to be configured are the ones which make your Qlik Sense Hub and NPrinting Admin Console shown without certificate errors in web browser:

You are currently typing in OnDemand extension: "https://NPrinting:4993" - that is not FQDN. and when you type it in in your web browser you will get SSL certificate error similar to the one below. You need to make sure that you can access QlikSense and NPrinting without having SSL cert error.

I have just checked I found one more thing that....the on demand is working fine if I access qliksense hub inside nprinting server. The issue is accessing qliksense hub outside of the nprinting server. Here is some dev tools error logs:

That is exactly for that very reason - SSL certificate issues!

So, I also want to confirm if the issue with qliksense server side or nprinting server side?

what is the next step to be done ?

Re: On Demand Button

Lech_Miszkiewicz — Mon, 24 Jun 2024 05:49:16 GMT

It is both servers. Both servers have to have SSL certificate configured for troubleless, seamless OnDemand workflow. This is because user authentication and authorization needs to happen in the background so no SSL errors can be allowed.

I gave you links to step by step setup of Qlik Sense certificates as well as NPrinting certificates. Have you read those links?

cheers

Also as a follow up - in the same section of the help site you may need to focus on this part to get better understanding of what is required: https://help.qlik.com/en-US/sense-admin/May2024/Subsystems/DeployAdministerQSE/Content/Sense_DeployAdminister/QSEoW/Administer_QSEoW/Managing_QSEoW/change-to-signed-server-proxy-certificate.htm

Okay. Then First I need to install OpenSSL.

As per reference URL I need to download Open SSL as below:

But I think this is not updated in help documents as I am unable to find any version "Win64OpenSSL_Light-1_1_0e.exe " on https://slproweb.com/products/Win32OpenSSL.html URL.

Please advise how I can choose the OpenSSL version from below list:

Re: On Demand Button

Lech_Miszkiewicz — Mon, 24 Jun 2024 08:01:25 GMT

Steps are:

get your system admin to create DNS names for FQDN (Qlik Sense & NPrinting)
get your system admin to obtain 3rd party trusted certificates (it can be 1 wildcard certificate for both sites) - requirements for those certificates are in the links provided earlier
get your system admin to convert for you certificates to required formats .crt .key .pfx (so you dont have to deal with OPEN SSL by yourself)

Regarding OpenSSL and converting certificates - You can use newer version of installer, but still ensure you first obtain 3rd party trusted certificate as self signed certificate will not work for you.
