Before enabling http(s) make sure you have the certification installed in your server in the pos domain name.

To check if the certificate is working go to https://yourdomain.com. If it shows green secured then the certificate is installed and we’re ready to use it.

To force redirect every user to https follow the below steps:

1. Inside pos codebase, you will find .htaccess file, open the file.
2. This file will have some codes like this:

       RewriteEngine On
   
       RewriteRule ^(.*)$ public/$1 [L]
   

   Keep a back up of existing code and change the content to:

       RewriteEngine On
       
       RewriteCond %{HTTPS} !on
       RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
       RewriteRule ^(.*)$ public/$1 [L]
   
   

3. Refresh your browser and check. It should redirect to https by default.
