NPrinting 18 Nov 2018 freezing

bobbydave — Fri, 03 Apr 2020 13:26:20 GMT

I've gone from NPrinting 18 Sept to Nov 2018 release

However when I try to open it and sign in, all good and it freezes then as below.

The timer at the top just freezes, its not rotating as if to show it is doing something.

Anyone encountered this issue?

TIA.

Hi,

It seems that the Qlik NPrinting Scheduler service is stopped. Please try to restart it. If it doesn't restart please reboot the server.

Best Regards,
Ruggero

Hi Ruggero,

My engine isn't coming online.

I've restarted the server and restarted all services. No difference.

I've activated the license, put in the license password when adding the engine. I just cannot get the engine to come online.

Hi,

From Qlik NPrinting November 2018 Release Notes:

Upgrade to November 2018
If you are upgrading to November 2018 you must:

Reinstall all your Qlik NPrinting Engines and providing a password for certificate exchange
Open the Engine manager in the Web Console
Open the detail page for each Engine and send the certificate after inserting the same password

you used during the engines reinstallation
Qlik NPrinting Engines stay offline until the certificate exchange is performed. Older Engine versions cannot
connect to a Qlik NPrinting November 2018 Server.

I suppose the problem is this.

Ruggero,

I put in the same password as I had during the installation from the cert and it saved.
But that didn't bringing it online. I removed the engine and readded and still no joy. I've no idea what else to try

I got the message Cert installed successfully but too quick to get a screen shot.

Ruggero_Piccoli — Mon, 26 Nov 2018 14:42:54 GMT

Hi,

At this point you could:

Check if there are some meaningful error messages in the logs
Open a support ticket in order to organize a remote call and check you installation

I have not other ideas.

If they are not installed please follow the instructions to install the Qlik NPrinting Engine again.

Hi,

Did you find solution to this issue? I have similar problem. I am setting up NPrinting from scratch. Engine doesn't come online & there are no errors in logs.

For those of you who are experiencing first time configuration and functionality issues, your issue is likely a planning, setup and configuration issue that is separate from the upgrade concern expressed in the original question in this discussion.

For new installs, please check the following configuration setup information.

https://help.qlik.com/en-US/nprinting/November2018/Content/NPrinting/DeployingQVNprinting/Planning-your-deployment.htm

https://help.qlik.com/en-US/nprinting/November2018/Content/NPrinting/DeployingQVNprinting/Installing-qlikview-nprinting-server.htm

NOTE: Restart the NPrinting server after upgrade

https://help.qlik.com/en-US/nprinting/November2018/Content/NPrinting/DeployingQVNprinting/Installing-qlikview-nprinting-engine.htm

NOTE: From November 2018 release and newer versions of NPrinting, there are additional steps required for installing/upgrading the NPrinting Engine and a new port 4997 that needs to be opened on your computer and network firewalls. See the following article and video tutorial for more information. https://qliksupport.force.com/articles/000059277

https://help.qlik.com/en-US/nprinting/November2018/Content/NPrinting/DeployingQVNprinting/Installing-qlikview-nprinting-designer.htm

NOTE: If you still have an issue with your initial setup and configuration of NPrinting and you have followed all the steps in the links above, then please start a separate thread since the solution will likely be completely different for new installations.

Hi,

I already have another thread started giving out engine log details. I didn't hear back from anyone there after posting logs.

NPrinting engine remains offline

If you are having issues still and if you have access to the Qlik Support desk based your support agreement I suggest submitting a support request to the Qlik Support desk so the issue can be investigated in greater detail.

Re: NPrinting 18 Nov 2018 freezing

bobbydave — Mon, 04 Feb 2019 14:19:38 GMT

This was never resolved.

I am still on June 2018 release.

I have been on to Ometis support who have been assisting but they couldn't resolve the issue. They then got Qlik involved who I had on a support call for over an hour with no resolution.

A JIRA was opened by Qlik for which I have received no call back or no JIRA request. This was logged about 10 days ago and still no contact from Qlik.

Re: NPrinting 18 Nov 2018 freezing

Frank_S — Mon, 04 Feb 2019 15:13:57 GMT

First check if your system resources are sufficient on both the NPrinting and QlikSense (or QV server is QlikView). If either have maximized resources, this could cause the appearance of 'freezing'.

ie: low hard drive space, insufficient memory resources. check the article below.

https://support-cdn.qlik.com/articles/000034936

If the issue is not resolved via your support via your support partner, ask them to escalate the issue particularly if this is your Production system. Contact your partner manager if needed.

Hope this helps.

Finally got this working this morning by changing the key in TLS 1.0

Disabled key was set to 1 and I changed it to 0

Enabled key set to 0 and I changed this to 1.

Only on the Client Key, not the Server key.

Reboot and engine came on line
