After several attempts installing Mautic on a VPS with Aapanel and Nginx, and assembling my own configuration file since the ones found online were not working, I got everything functioning except for the tracking pixel. I believe there is an issue with my redirection configuration or something similar.

Request to: [https://my.domain.com/email/pixel.gif](https://my.domain.com/email/pixel.gif) Results in: 404 Not Found nginx

While: [https://my.domain.com/index.php/email/pixel.gif](https://my.domain.com/index.php/email/pixel.gif) Works perfectly.

I have already tried the following location blocks:

location ~ email/(.\*).gif { try\_files $uri /index.php?$args; }

location ~ mtc.js { try\_files $uri /index.php?$args; }

location ~ mtracking.gif { try\_files $uri /index.php?$args; }

location ~ ^/email/.+.gif$ { try\_files /www/wwwroot/my.domain.com$uri /index.php?$args; access\_log /var/log/nginx/pixel.log;  
}

Note: I’m going to add my Nginx configuration in another post, so it looks better

Technical details:

- 4.5GB KVM VPS
- Cron jobs enabled
- PHP 7.4
- Panel: Aapanel
- Nginx
- No relevant error logs on the server related to this.

I would greatly appreciate any help in resolving this tracking pixel issue.

Hi,

```auto
 location ~ focus/(.*).gif {
        try_files $uri /index.php?$args;
    }

    location ~ email/(.*).gif {
        try_files $uri /index.php?$args;
    }

```

Try these two.

Regards, M.

It worked perfectly, although not directly in the config file but in a special section that Aapanel has for URL rewriter, a complete guide on what the config file for Aapanel with Nignix should be like is definitely missing, since it has a very different structure

Thanks very much buddy
