Why is node creating multiple server in cpanel
The issue is the .htaccess in the url directory.
you need to adjust the .htaccess file to access the exact server and port
E.G (sample .htaccess file code)
DirectoryIndex disabled
RewriteEngine On
RewriteRule ^$ http://127.0.0.1:XXXXX/ [P,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ http://127.0.0.1:XXXXX/$1 [P,L]
Now, replace XXXXX with the port your Node.js application is working on.
