How to resolve Verification Error - x Qlik NPrinting webrenderer can reach Qlik Sense hub error

[Frank_S]

This article describes how to resolve the NPrinting connection verification error:

x Qlik NPrinting webrenderer can reach Qlik Sense hub error

Environment

• NPrinting: all versions
• Qlik Sense: all versions
  • multi-node QS proxy environment
  • NLB (Network Load Balancer or Alias URL) server address used in front of cluster of Qlik Sense proxy nodes (which are linked to a Virtual Proxy. Proxy nodes will not work with NPrinting unless they are linked to a QS virtual proxy)

Resolution

• Although it is possible to use an NLB address in front of your QS proxy nodes that are used by NPrinting, the error generated in the NP connection verification process will appear as described in the article title
• This error can safely be ignored as this does not affect generation of NPrinting connections
• To eliminate the 'error' message, you would need to update your NPrinting connection to use a virtual proxy node address/computer name behind the NLB address . It must be the computer name and not an alias url).
• The proxy node used must be linked to a virtual proxy with the following required attribute
  
  • Microsoft Windows NTML authentication on the Qlik Sense proxy. (SAML and JWT are not supported. If your virtual proxy uses SAML or JWT authentication, you need to add a new virtual proxy with NTLM enabled for Qlik NPrinting connections).
  • A link between the proxy node and virtual proxy.
  • For all NPrinting to Qlik Sense requirements visit https://help.qlik.com/en-US/nprinting/Content/NPrinting/DeployingQVNprinting/NPrinting-with-Sense.ht...
• If a DNS name is involved and the Qlik Sense certificates are generated using that DNS name, try disabling the "Apply Qlik Sense server certificate validation" checkbox.

I've tried but it still doesn't works. Nprinting is linked to another server Qliksense and it works fine. This second Qliksense server is November 2023.

In my case the below setting solved the issue:

In the NP webconsole, go to Admin>Settings>Task
In the Security section, uncheck the box for 'Apply Qlik Sense server certificate validation' and click update. If you are publishing reports back to the QlikSense hub this is needed, otherwise you don't need it turned on.

@svuradi Thank you, that was helpful.

This is my solution too with NP May 2025 SR1:

"
