I want to run Presta behind an Nginx reverse proxy. Presta 8.2.1 is running on Nginx 1.26.3. I’ve prepared:

  • Reverse proxy config: https://pastebin.com/Xcx2s93f
  • Presta (backend) config: https://pastebin.com/q1V8y4zx
  • In Presta’s database, in the ps_shop_url table, I set the domain and domain_ssl columns to test-proxy.example.com and test-proxy.example.com respectively. By default, / in physical_uri.
  • Backoffice works perfectly. In it, under Shop Parameters → Traffic & SEO, I have:

Set up URLs:

  • Friendly URL → Yes
  • Redirect to the canonical URL → 302 Moved Temporarily

Set shop URL:

  • Shop domain → test-proxy.example.com
  • SSL domain → test-proxy.example.com
  • Base URI → /

The problem I deal with:
When I go to test-proxy.example.com, I get a redirect loop from test-proxy.example.com to test-proxy.example.com with a 302 status code. If I change the "Redirect to the canonical URL" option in the backoffice to 301, then I get a redirect loop with a 301 status code.

Visiting any non-existent URL, e.g. test-proxy.example.com/test, generates the correct response /index.php?controller=404.

Visiting any existing URL, e.g. test-example.com/about-us, causes a redirect loop: /about-us/ 302 → /about-us 302 → /about-us 302 → /about-us and so on in a loop.

If I only change in the database, in the above-mentioned table, test-proxy.example.com in both columns to presta-us.example.com, then the front works, but there’s a problem with the cart. This is understandable behavior.

Of course, when I completely delete reverse proxy, presta-us.example.com works smoothly like it should. :)

I have no idea what’s going on anymore. I checked the values of the headers passed by the proxy. I also prepared a script that displayed the header values: https://pastebin.com/tmT9R2Jd

The goal:
Working Prestashop front behind nginx reverse proxy.
I also set up Wordpress behind reverse proxy, which works - frontend/backoffice - like a charm.

I tried with clean presta 8.2.1 and also 1.7.8.10. My config works perfectly front/backoffice, so the problem is probably with some module which gives “SEO & URLs” option in the backoffice –> Preferences.

Full updated code (you can use nginx snippets to have clean configuration):
`server {
server_name proxy.example.com;
return 301 https://proxy.example.com$request_uri;
}

server {
listen 443 ssl http2;
server_name proxy.example.com;

# SSL
ssl_trusted_certificate /etc/letsencrypt/live/proxy.example.com/chain.pem;
ssl_certificate /etc/letsencrypt/live/proxy.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/proxy.example.com/privkey.pem;
include snippets/ssl-config.conf;

# tutaj sie zaczyna calosc proxy dla sklepu
location ^~ /admin9254z9q7u {
    proxy_pass https://presta-czysta-osiem.example.com;
    proxy_ssl_server_name on;
    proxy_ssl_name presta-czysta-osiem.example.com;

    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Proto https;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header Connection "";

    access_log /var/log/nginx/domains/proxy.example.com.log combined;
    error_log  /var/log/nginx/domains/proxy.example.com.error.log info;
}

location / {
    proxy_pass https://presta-czysta-osiem.example.com;

    proxy_redirect off;
    proxy_http_version 1.1;

    access_log /var/log/nginx/domains/proxy.example.com.log combined;
    error_log  /var/log/nginx/domains/proxy.example.com.error.log info;
}
