Hello Qlik Users!

With the recent change to Qlik Sense Desktop, we have seen some users facing issues with authentication. Users are reporting the following error message:

Failed to authenticate against the selected server. Please make sure your internet connection is working and try again.


There are a few reasons why this error could occur.



The firewall is blocking the required ports.

Contact your local IT/network administrator and ensure that the following URLs can be reached using https (port 443): *, * and *

Version of Qlik Sense Desktop.

Verify that you have the most up to date version of Qlik Sense Desktop installed.

A proxy is being used to access the internet.

It may be necessary to bypass the Proxy to log on and authenticate or to contact your local/IT network administrator to ensure the appropriate ports are opened.

A VPN is being used.

Disconnect from the VPN or contact your l local/IT network administrator to ensure the appropriate ports are opened.

The incorrect license was granted in Qlik Sense Enterprise.
