Hi @jimchan1234 

when facing such issues I usually check the Windows Event Viewer.

It should report the problem with some info.

I also suggest looking at the logs, usually found in C:\ProgramData\QlikTech\WebServer\Log

20240507T101248.108+0800 Error System.Net.HttpListenerException (0x80004005): Failed to listen on prefix 'http://+:443/qvdesktop/' because it conflicts with an existing registration on the machine. || at System.Net.HttpListener.AddAllPrefixes() || at System.Net.HttpListener.Start() || at QlikView.AccessPoint.HttpServiceComponent.Init(String[] args) || at QlikView.AccessPoint.HttpServiceComponent.Start(String[] args)

It seems that the 443 port is already taken by another application. Maybe you have IIS running and using this port?

I suggest you check with your systems administrator the situation.

This command should help you find the application that is using the port:

netsh http show urlacl
