The Different between Root at Listen 80 and Listen 443

Hello Guys, May i know what is the different between both of root at Listen 80 and Listen 443? I have problem with access my HTTPS site. I got Error 404 if i set my 443 to On. My page is secure and the CA is active. (/var/www/ But my website can’t access. If i don’t activate my SSL, the website is fine but i have already setting my General Wordpress to change it’s url become Because of that i can’t acess it if i am not change my Listen into 443. (/var/www/

Am i miss something? Or am i make a mistake?

My step is :

  1. Initial setup Ubuntu.
  2. Install LEMP.
  3. Install Virtual Host.
  4. Install SSl.
  5. Install Wordpress.

Thank you, Frans W

The main difference between 2 ports Listen 80 = HTTP = Non SSL Listen 443 = HTTPS = SSL

Please check the following tutorial and see if you missed something or not How To Install an SSL Certificate from a Commercial Certificate Authority

also you shouldn’t change url in your wordpress general settings to https. post your nginx virtual host file configuration to see if there’s something wrong.
