Discussion Board for collaboration on Qlik NPrinting.
NPrinting engine remains offline & status does not change to online. I checked the logs & below error appears in scheduler logs:
Exception caught Qlik.NPrinting.Repo.ServiceException: Lef File Server Unreachable
I have activated the license offline & it says activation successful.
Has anyone encountered this error before?
Was it an upgrade to Qlik NPrinting November 2018 or a fresh install? Has it ever worked before?
I don't think the error message you see is causing the problem. I think it's just a check failing at the service startup.
If you go to the WebConsole -> Admin -> Engine Manager and Edit the configuration for your engine, do you see a text box at the bottom asking to enter the Password for the certificate private key?
This is a fresh installation & it never worked.
I see a text box at the bottom asking to enter the Password for the certificate private key on web console.
But when I enter the password, I get below screen
I get this error sometimes & sometimes it says certificate sent successfully. Engine still remains offline.
I checked all above mentioned parameters & they seem right. I am using server name without domain as suggested in other posts.
Any idea what is causing this issue or where shall I look into.
I would suggest the following steps:
Qlik.NPrinting.Engine 126.96.36.199 Qlik.NPrinting.Engine.EngineService 20190109T111811.187+01:00 INFO QLIKSERVER3 0 0 0 0 0 0 0 0 Starting up Engine service

Could you also make sure to disable your antivirus and check if you have any Proxy configured on your machine to make sure nothing interfers the communication between the Engine, RabbitMQ and Scheduler?
Hope this helps!!
Could you try the following steps:
Starting up Engine service Certificates exchange HTTP server listening on http://localhost:4997/
Starting RabbitMQ connection using certificate E7BAD4E2CD29F8B742EB2B1766C224948E109755 Starting Engine Consumer Engine Consumer started successfully Slave Engine Service started successfully
In addition, could you make sure to disable any antivirus and make sure that you have no proxy enabled on the machine to make sure nothing is interfering?
Hope this helps!
Can you please explain what is MMC & how do I get to it?
To open mmc press [windows key]+R to open execute panel, type 'mmc' (without quotes) and press enter.
In File->add/remove components add 'certificate' and select 'personal account' in the next dialog, accept.
I don't see a certificate called client_engine, I can see below certificate. Not sure if its same.
When I follow steps given by you, my engine log does not show below two entries
Starting Engine Consumer
Engine Consumer started successfully
After Starting RabbitMQ connection using certificate it directly shows Slave Engine Service started successfully
