SSL

Install SSL certificate on your hosting/VPS

You need to install an SSL certificate on your hosting/VPS first. You can purchase an SSL certificate or use free SSL, for example Let's Encrypt.

First you need to change APP_URL=http://domain.com to APP_URL=https://domain.com in your .env file.

Option 1: Add CORE_ENABLE_HTTPS_SUPPORT=true to .env.

Option 2: Add these lines to .env

CORE_FORCE_SCHEMA=https
CORE_FORCE_ROOT_URL=https://domain.com
CORE_ENABLE_HTTPS_SUPPORT=false

Option 3: If you are using Shared Hosting, you can Force HTTPS Redirection for your domains. Check this article.

If it doesn't work, you have to config it in .htaccess or Nginx config.
