The NPrinting Server Web Console Publish Task completely hangs in the processing of an NPrinting Server Web Console Publish Task execution
Environments:
Any Supported NPrinting Web Console server environment
Possible Causes:
System Requirements not met: For example, sharing the NPrining server/engine service account.
Unsupported items, unsupported platform or Incomplete configuration
QV and or QS server resources are at full capacity: near 100% utilization
QV and or QS services are not started
Section access
IE Enhanced Security is enabled
Folder permissions are not enabled for the NP service account
Older versions of NPrinting with Known "connect failed" issues (November 2019 and earlier versions)
Checklist to troubleshoot and solve this issue:
Ensure that all respective system requirements are met: Disregarding system requirements will cause hanging behaviour and connection issues. ie: Unsupported version of QlikView, Qlik Sense
Remove all Unsupported Items including alternate states, sheet/document triggers, always one selected list/multi box properties from a copy of the QVW and use the copy for reporting purposes. For detailed steps and workarounds, please visit the links below:
Dedicated Domain NPrinting Service Account must be created for NPrinting server service account when connection to QlikView (not required for NPrinting connections Qlik Sense from June 2019 and later versions of NPrinting). Do NOT use the QlikView service account to run the NPrinting server services as this can cause the QV and or NP servers to crash or hang. Configuring the NP service account: Windows Qlik NPrinting Engine service administrator
-Log on as the NP service account. -Use 'File > Open in server" using the QlikView Desktop and connect to any QVW to pull the assigned license lease to the QlikView Desktop.
Destinations: Ensure that the NPrinting Service account has permissions/access to local folders and network folders if using local NP connections. These Windows 'share' and 'security' permissions are necessary to configure if you intend to distribute NPrinting reports to a network or local destination. To configure 'Destinations' visit Distributing reports to folders
Section Access: If you are using Section Access in your QVW or QVF, it must be NTLM section access and the NPrinting service account as well as the identity used in the NPrinting connection should be added to the section access load script as ADMIN access. Further you must use QVP connections when using Section Access. See https://community.qlik.com/t5/Official-Support-Articles/NPrinting-Reports-Tasks-and-Connections-that...
Disable IE Enhanced Security of the NPrinting and QV Access point servers:
Ports: Check that the necessary Ports are managed accordingly (see the section below and 'Related Content' section of this article) if you have a network or computer firewalls enabled
Report preview fails with error: Attempt to preview the report with the report task. If the report fails to preview normally and an error is generated, the problem is with the NPrinting report and not the task. See possible solution here: NPrinting Qlik Sense Images Fail to Render Export Generate or Preview
Server compatibility: Ensure that the NPrinting and Qlik Sense and or QlikView servers are not running on the same Windows server computer. SeeSupported and unsupported configurations
Server performance: Check the QlikView Server and Qlik Sense server performance. If those servers resources are maxed out/fully utilized ie: CPU and Memory nearing 100 percent usage, NPrinting may fail to open any QVWs or QVFs.
Restart Servers: Check that the QlikView Server and Qlik Sense server services are fully operational and running. Restart these services on a regular basis to mitigate performance issues related to Windows Memory leaking. Rebooting servers on a regular basis is recommended for any Windows Server.
Disk c:\Drive space low. Make sure to clean up temp and other log folders or add additional disk space
Keep in mind: In many cases due to certain defect fixes, upgrading often resolves connection issues when running older versions of NPrinting assuming thatthe information in this article above is first fully addressed. It is suggested that you upgrade to the most recent version of NPrinting available from the Qlik Support downloads site to leverage any recent bug fixes and performance enhancements. Always check corresponding product release notes and NPrinting system requirements before upgrading.
