Resolution

Verify if your environment has a working internet connection to the license backend and that all required ports are enabled. See Qlik Sense Ports.

If all ports are open and internet connectivity is confirmed, verify that you are using a supported TLS version. See Supported TLS and SSL Protocols and Ciphers for details.

Using the above article as a guide you can either:

use IISCrypto (a third-party software) to deploy the IISCrypto Best Practice
or you can run the PowerShell script containing the recommended TLS and cipher settings included in TLS and SSL Support in Qlik Sense: How to configure Qlik Sense.
