Hi there i changed panel port from 8090 to 8443 because I use cloudflare then removed port with this guide GUIDE LINK

My rewrite rules

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^/?(.) https://%{SERVER_NAME}/$1 [R,L]
RewriteRule ^(.
)$ HTTP://cyberpanel/$1 [P]

Whats the problem?

dig forum deeper

Change:
RewriteRule ^(.)$ HTTP://cyberpanel/$1 [P]
Into:
RewriteRule ^(.*)$ HTTP://cyberpanel/$1 [P]

It’s missing a *
