User or certificate X509N:<S>CN=QlikClient generates authentification error


I have Qlik Sense installed and everything works fine. I installed the november 2017 release.

Within my Windows event viewer I keep getting a message every x hours.

It looks like a Qlik Sense service tries to authenticate user 'Qlikclient' (which I don't use myself) and which does not succeed.

I don't use Kerberos (unchecked in the QMC).

In folder C:\programdata\Qlik\Repository\Exported Certificates\.Local Certificated I tried to delete all *.pem files. It looks like this client.pem has something to do with it. But when I delete these files and restart all services, these files are regenerated again and used.

What can I do to prevent the system generating these errors?

Thanks for help,

I'm still seeing them post-upgrade too.


Hi, we do experience the same issue there, we also install the last update available (september2018 with patch 1), and we still have the issue. Does someone here have something new about this?

Same issue happened in November 2018 Patch 2.

Does anyone have any solution please?

I am getting this error today.  There were over 500 generated so far.

My install was done ( I think June 2019 release) in the last month.


Someone at Qlik please respond directly.

What is the issue?
