要将所有请求重定向到非www，请在网站的.htaccess文件的开头添加以下行：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

因此，编辑您的.htaccess文件的版本：

# Force www to non-www
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

RewriteEngine on

PassengerAppType node
PassengerStartupFile /home/username/public_html/App.Next/server.js

# DO NOT REMOVE. CLOUDLINUX PASSENGER CONFIGURATION END

RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-SSL} !on
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%1%{REQUEST_URI} [R=301,L]
