NPrinting 17 to Qliksense connection For Production environment

[#1]

Hi Folks,

       I have installed NPrinting 17.3 with Domain\user on Machine1 and Installed qliksense on Machine2. This two machines are under on same domain. Domain\user also part of root admin on qliksense server with token allocated. certificate also export and installed on machine1

Below ports are opened

• Ports 4242 and 4243 must be opened inbound on the Qlik Sense server computer (the computer where Qlik SenseRepository Service (QRS) and Qlik SenseProxy Service (QPS) are installed).
• Ports 4242 and 4243 must be opened outbound on Qlik NPrinting Server and Qlik NPrinting Engines.
• Port 4747 must be opened inbound on the computer where Qlik SenseEngine Service (QES) is installed.
• Port 4747 must be opened outbound on Qlik NPrinting Engines.

and Port 80,4248

But NPrinting shows error while creating connection from Qliksense

ex:

Proxy address:  http://machine2/‌ and http://ip/

appID:123

Identity:Domain\user

i tried http and https but same error was occurred.

How can i resolve this issue any suggestion please...

Login from Machine 1 to QlikSense Hub as NPrinting account and try to open a QlikSense app. Can you do it without issues? Where is a QlikSense application sitting? In Published stream or MyWork? If it is MyWork area of different user NPrinting will not be able to access this location.

Hi lech_miszkiewicz,

       Qliksense Hub and app can be open on NPrinting Server but on Http:// and port 443 https port is blocked .

So my doubt is NPrinting can create connection by http ??

[Lech_Miszkiewicz]

I am running out of options here. I tested with proxy address like: http:/XXXX/ and it worked for me. So i guess https is not required. The thing is that my https is still working so 50/50 chance it is port 443.

I am not sure about ports though - Help document does not say anything apart from you already stated.

We did all basic troubleshooting.

I would try to get qlik support on this - they will understand your logs better.

Let us know when you find a root cause of this issue - it will be good to know what was it.

good luck

Lech

Did you import a Certified Generated from Qlik Sense?
