Hope you have set up the DNS for the Qlik sense Setup.
Meaning, if you have used the wildcard certificate *.ABC.com
then make sure you have used the DNS name for the qlik Sense Server, something like
If you still use the computer name or IP address to access the HUB and QMC then you may see that error.
For those wondering, the issue was with how I was importing the SSL Certificate. Ensure that you don't mark the private key as exportable when importing the certificate. After making this change the SSL Certificate was properly applied.
I was able to debug this by setting the Qlik Sense logging flags to verbose (through the Qlik Sense QMC) and then reviewing the logs located @ \ProgramData\Qlik\Sense\Log\Proxy\Trace\.
