On Demand - unable to connect to server

[danielgargiulo]

@Frank_S  see below for the question in a new thread

Issue: When we put selections in the Qlik App and no filters in NPrinting then we get the error (see images below). Note: When we have filters set up in NPrinting on the report and User and NO selections are made in the Qlik App then it runs fine

Qlik Sense Enterprise: Nov 2018 - Secure Site

Qlik nPrinting: April 2019 - Unsecured Site

Any thoughts are appreciated.

Thanks @danielgargiulo 

This is great info and appreciate that you started this new separate thread.

1. Make sure that your Qlik Sense hub address is added as a trusted origin in the NPrinting web console under Admin>Settings>On Demand>Trusted origins

make sure to add your Qlik Sense server address to the trusted origin list

2. Check the connection string in the On Demand report object in your Qlik Sense app. You will need to re-associate your NP server connection to the NP App. If a / is not appended to the end of the server connection string, please add it.

ie: ttps://NPrintingServer:4993/

For more information on point 2, check this article https://support.qlik.com/articles/000065283

Refreshing the connection inside the On Demand object should fix it.

Hey,

Point 1: we have added it to the trusted origins however the address keeps shortening to their friendly name eg removes the hub part. 

Point 2: we have now added the '/' however are still experiencing the same issue.

Try adding and configuring a second On Demand object. 

It may be necessary to replace the object entirely to get it to work normally.

If replacing the object works, then simply remove the original object and continue with the new one.

If that doesn't work, then you will need to contact the Qlik Support desk or your Qlik Support partner to look into it further. Hopefully my final suggestion to add a new object and replace the original will work for you however.

Hi Frank,

Thanks for the support to date. We have tried adding a new object and get the same error. We have a case logged with Qlik support.

The link you sent had a further link to this article: https://support.qlik.com/articles/00006055

- This article has the section below. The authentication providers is OKTA (Saml), could that cause an issue? It seems strange if it is the issue as it works fine when no filters are applied in the Qlik App.

Un-supported authentication methods are as follows:

1. JWT and QS NP On Demand
2. SAML and QS NP On Demand

NOTE: Windows NTLM auth is the only supported authentication method with Qlik Sense with NPrinting On-Demand. Remove any 3rd party or Qlik On-Demand Extension before installing new version. 

Thanks,

Dan

Ok...you just gave me another clue.

"It seems strange if it is the issue as it works fine when no filters are applied in the Qlik App".

I missed this point in your original description above.

If it is working with no selections but fails with selections, you need to follow this article I just wrote today:

How to manage Qlik Sense NPrinting On Demand "Request Failed" message https://support.qlik.com/articles/000074356

Otherwise, we'll have to help you directly in the support case that you submitted if this latest suggested solution doesn't work for you.

HI Frank,

I have just checked again and we have no filters on the report or user.

Ok...I've left a comment on the case for my APAC colleagues regarding this thread and advised them to review this thread as well.
