Qlik Sense NPrinting - Cannot Find App?

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

Hi there,

New to N'Printing, and not sure how to handle this error.

I have installed the engine and server packages on the same machine (for testing purposes), Qlik Sense Enterprise is on another server.

When I try and run verification of the connection I get an 'X' next to: "Get App information from QRS on the "Proxy Address" for the "Sense App ID"." (attached screenshot).

The app I have targeted on the enterprise platform exists in the RootAdmin's (username - QlikInstaller) work folder. I am creating the connection using the same credentials.

Anyone have any ideas?

Thanks,

This is on AWS and all ports are open. Based on the error it almost looks permission related, but I don't understand why as the user is rootadmin / admin across both Qlik Enterprise and NPrinting. Does the Admin user of NPrinting need some sort of added roles or permissions?

RootAdmin permision is only set in Qlik Sense QMC so it is only related to Qlik Environment (not NPrinting environment). Since other verification steps are coming through ok i do not think it is permission setting.

ohhh, btw - QlikInstaller is different user than Qlik Sense service account ? ...as per requirements, isn't it?

Try this.

1. Assign a token to the NPrinting service account (which should also be root admin on the Qlik Sense server as per requirements)

2. Login to the Qlik Sense hub where the Sense App is available from

3. Open the Sense app and capture the Sense App ID from the browser's address bar.

If you are unable to open the sense app as the NP service account and view the app normally, then it is possible that section access is used an the NP service account must be then added to the load script of the Sense App.

You must select the 'section access' check box on the NP connection page as well if section access is in use. https://help.qlik.com/en-US/nprinting/February2019/Content/NPrinting/DeployingQVNprinting/Section-access.htm

If you can't even open the sense hub with the NP service account or cannot open the Sense app after logging in then this could be where your issue lies.

Note that the NP service account should be used as the

NP 'connection identity' when testing this issue as well to simplify the analysis of the issue.

Hope this helps you to narrow down the issue.

When setting up the users I have given my QlikInstaller and QlikService accounts both the same level of access - run as batch, local admin and both RootAdmin on Qlik Sense.

Ruggero - I checked the documentation and all of my certificates have the correct hostname (not the AWS thing)

Frank -

1. Assign a token to the NPrinting service account (which should also be root admin on the Qlik Sense server as per requirements)

The service account (QlikService in both NPrinting and Enterprise) didn't have a token so I have allocated.

2. Login to the Qlik Sense hub where the Sense App is available from

I Logged in and created an app using Qlik Service.

3. Open the Sense app and capture the Sense App ID from the browser's address bar.

Copied the GUID.

If you can't even open the sense hub with the NP service account or cannot open the Sense app after logging in then this could be where your issue lies.

Note that the NP service account should be used as the

NP 'connection identity' when testing this issue as well to simplify the analysis of the issue.

Used QlikService as the connection account.

Still the same issue...

One thing I noticed when going through that which looked odd to me is that within the QMC I now have multiple QlikInstall and QlikService accounts which are split but different domains (Magdev and Magdev.net - image attached)

So I assigned tokens to all of those accounts, and made them all RootAdmin and now it seems to work! So it looks like the issue is domain related somehow, I shouldn't have multiple users for sure!

Have I perhaps done something wrong when setting up the certificates? I don't recall adding the domain anywhere on the NPrinting setup, and all machines are within the same domain (Magbi.net)

Thanks,

Thomas

Looks to me that the NPrinting server is using the NetBIOS whereas the Qlik Enterprise server is using the DNS name - not sure why this is happening?

OK figured out the answer now.

It seems from NPrinting you are asked to specify the domain\username

As long as NPrinting can contact the Qlik Enterprise server Qlik will go off and create a new user. In my case my user directory was Magbi (for some reason) from the install of Enterprise. On the NPrinting side when I went to validate I was using Magbi.net\QlikService. Enterprise will just go and create a new user, with whatever domain name you choose, literally anything! So I ended up with the same user twice, with differing domains. Changing the validation to use magbi instead of magbi.net I end up hitting the correct domain / user combination.

I'm new to NPrinting, but I must say this is sort of odd. I can specify any users name in the connection and access their apps? No password validation SSO required..Doesn't seem very secure.

Hi,

You specify the domain user in the connection but Qlik NPrinting will be able to connect and retrieve Qlik Sense data only if that user is RootAdmin in QMC and has access to the connected app. So if you insert a wrong user in the connection (one not authorized for example) the connection will not work. You see this in the Run Verification.

Qlik Sense creates the user when the user tries to connect, it is Qlik Sense way of working. That user cannot do nothing until you authorize it. When Qlik NPrinting tries to connect it works at the same way and Qlik Sense creates the Qlik NPrinting user.

Ruggero

The domain account that you use to run the NP server services (Engine, scheduler and web engine) must be a member of the domain that the NP server and QS servers are members of. Originally you probably imported certificates while logged in as the domain account that is a member of the same domain of the QS and NP server. Once you made that user rootadmin and assigned the token, it appears to be working now as designed.

https://help.qlik.com/en-US/nprinting/February2019/Content/NPrinting/DeployingQVNprinting/User-accounts.htm

To connect Qlik NPrinting to Qlik Sense apps:

The Windows user account that runs the Qlik NPrinting Engine service must have:
- RootAdmin authorization configured in the QMC.
- A domain user account that is a member of the same domain as the Qlik NPrintingserver and the Qlik Sense server.
