Enabling and disabling Let's Encrypt on nginx server caused 404 error

Hello, I set up ssl using lets encypt for an nginx site. After forge indicated that is was installed the site returned a 403 error, I then uninstalled let's encrypt and now the site returns a 404 error.

Here is the nginx config

# FORGE CONFIG (DO NOT REMOVE!)
include forge-conf/not_my_real_site_name/before/*;

server {
    listen 80;
    listen [::]:80;
    server_name not_my_real_site_name;
    root /home/forge/not_my_real_site_name/web;

    # ssl_certificate_key
