nginx config not available and Error code: rewrites_not_executed

Hi @ironman199xx,

Thank you for your message.

I made a video showing how to configure Nginx. Please check them out. The reason why it doesn’t work for you is probably related to the file where you added new rules.

Best, Mateusz

Thanks for your answer, but I have tried configuring according to your video instructions many times, and the configuration can’t seem to pass nginx’s syntax check. Please provide me with more solutions to solve this problem. I have worked hard for 2 weeks to convert images to webp, but it seems that my nginx configuration is not correct. I know your plugin is very good because I have used many image conversion plugins before, and I believe you can help me solve my problem. I configured the site on a VPS using EasyEngine, and nginx runs in a Docker container.

@ironman199xx In the first message you sent the contents of the default.conf file. For my Nginx server, I had an individual Nginx configuration file for each site. Maybe this is the source of the problem?

Good morning! To have a better understanding of how my Nginx server works, please take a minute to read this Nginx configuration guide: https://github.com/openresty/docker-openresty/blob/master/README.md#nginx-config-files.

If you would like to have direct access to my server to help solve my issue, I can provide you with the server’s IP and root account details. Just send me an email, and I will share my account information with you through that.

@ironman199xx I cannot access your server. This is against the WordPress forum rules. I can only help you here on the forum and my help is based on my experience. I tested many Nginx servers and had no similar problems. What I can do is try to help you theoretically – we must respect the rules of this support forum.

In my opinion you added the rules in the wrong file. Please see what my configuration file looks like:

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name demo.mattplugins.com;

    client_max_body_size 64M;

    access_log /home/domains/demo.mattplugins.com/logs/access.log;
    error_log /home/domains/demo.mattplugins.com/logs/error.log;

    error_page 404 /index.php;

    # BEGIN Converter for Media
    set $ext_avif ".avif";
    if ($http_accept !~* "image/avif") {
        set $ext_avif "";
    }

    set $ext_webp ".webp";
    if ($http_accept !~* "image/webp") {
        set $ext_webp "";
    }

    location ~ /wp-content/(?<path>.+)\.(?<ext>jpe?g|png|gif|webp)$ {
        add_header Vary Accept;
        expires 365d;
        try_files
            /wp-content/uploads-webpc/$path.$ext$ext_avif
            /wp-content/uploads-webpc/$path.$ext$ext_webp
            $uri =404;
    }
    # END Converter for Media

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_param PHP_VALUE open_basedir="/tmp:/home/domains/demo.mattplugins.com/public_html";
        fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
    }
}

server {
    if ($host = demo.mattplugins.com) {
        return 301 https://$host$request_uri;
    }

    listen 80;
    listen [::]:80;

    server_name demo.mattplugins.com;

    return 301 https://demo.mattplugins.com$request_uri;
}

This file is located in the following location:
/etc/nginx/sites-available/demo.mattplugins.com

I have an idea for a little test. Please add these rules in the Nginx configuration instead of the ones you have (I added a test header there):

# BEGIN Converter for Media
set $ext_avif ".avif";
if ($http_accept !~* "image/avif") {
    set $ext_avif "";
}

set $ext_webp ".webp";
if ($http_accept !~* "image/webp") {
    set $ext_webp "";
}

add_header Test-header "OK!";

location ~ /wp-content/(?<path>.+)\.(?<ext>jpe?g|png|gif|webp)$ {
    add_header Test-header-img "OK!";
    add_header Vary Accept;
    expires 365d;
    try_files
        /wp-content/uploads-webpc/$path.$ext$ext_avif
        /wp-content/uploads-webpc/$path.$ext$ext_webp
        $uri =404;
}
# END Converter for Media

After adding these rules, please give me the URL to your site. I will check if the test headers are visible on the page.

Thank you very much. Finally, after many days of trying, I have successfully converted the images to webp using your plugin. My nginx configuration file is located at /usr/local/openresty/nginx/conf/conf.d/main.conf, and here is its full content after being configured according to your instructions.

I hope it will be helpful for others, like me, who are working with your plugin. Thank you once again.
