[Tutorial] How to setup and login to OpenLiteSpeed webadmin console

It does not lead to the cyberpanel page.
Leads to domain index.html.
This guide does not work on a new 1.9.1 installation:

Port 8090 conflicts with CF. Either you use CF with domains or CyberPanel admin login panel. At the same time, you can not use. CF has set up new hubs in Europe and may now be using CF 8090 proxy port for CF.
I have installed CyberPanel 2 times and each installation has the same error.

Guide:

Need to update.
How do I change the default CyberPanel login port from 8090 to another?
For me, the IP CF is different 104.27.174.39.
