NPrinting connection fails due to QlikView Desktop HTTP tunneling errors

[Frank_S]

Not able to perform a successful connection verification in NPrinting Feb 2020 when making a QVP connection
QVP connection encounters a tunneling error resulting from the setting shown below:

Environment

NPrinting Feb. 2020

Resolution

• Verify that port 4747 is open for communication
• Remove any local security policy which restricts QlikView desktop communication.
• In this case, remove the checkbox show and switch the policy so that it is 'undefined'

Cause

• Change made to default active directory policy which cause inference with NPrinting Connection success via the QlikView desktop
