Installed Cyberpanel fresh. Everything is working and I can access the panel via IP:8090.
Also, I added A record from Cloudflare to my server IP for mywebsite.com.
I wanted to access the panel via hostname. So I created a new website as panel.mywebsite.com first. Then issued SSL for hostname for the same domain panel.mywebsite.com - everything worked.
You’ll need to modify the panel’s prot to access Cloudflare’s supported ports
For example: 443|2053|2083|2087|2096|8443
Let’s assume that it is: 2083
Then you can access the https://panel.example.com:2083
