Running own website alongside QS web server

[#1]

We have a Qlik Sense server installed, a default installation, so it uses the QS Web Server. Qlik is working on port 80 and 443.

I want to run a website in IIS op port 80 (http) and 443 (https), but cannot do this.

IIS will stop (or then QS web server).

Is there a way to get this running? Can i run my own website under the web server of Qlik?

Or can I do something to run the website in IIS?

Had contact with Qlik helpdeks, and they confirmed that this is not possible (yet).
