The Qlik Sense Management Console and Hub do not load and reviewing the Qlik Sense Proxy logs (C:\ProgramData\Qlik\Sense\Log\Proxy) shows:
Proxy will NOT be listening to port 443, likely bound by another process An attempt was made to access a socket in a way forbidden by its access permissions.
Resolution:
The port required by the Qlik Sense Proxy is likely being bound by a different process such as a third party web server.
Verify what process is using the port and terminate or reconfigure the software as required.
See How to check which program is using a specific port for details.
