Tracking gives 404 - Please share nginx-settings

Could you please share your nginx-settings?
Because when I enable Tracking on our site I only get a 404.

This is the generated URL: http://www.audioflick.net/podlove/file/144/s/debug/AF11_bloodsport.mp3

And this is the part from my nginx-config:

       location / {
                try_files $uri $uri/ /index.php?$args;
                fastcgi_read_timeout 300;
       }
       location /podcast_episodes {
                autoindex off;
       }
location ~* (mp3|m4a|ogg|oga|opus|flac)$ {
    add_header Content-Disposition "attachment; filename=$1";
}

# Ensure requests for pagespeed optimized resources go to the pagespeed handler
# and no extraneous headers get set.
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" {
  add_header "" "";
}
location ~ "^/pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon$" { }
location /ngx_pagespeed_statistics { allow 127.0.0.1; deny all; }
location /ngx_pagespeed_global_statistics { allow 127.0.0.1; deny all; }
location /ngx_pagespeed_message { allow 127.0.0.1; deny all; }
location /pagespeed_console { allow 127.0.0.1; deny all; }
location ~ ^/pagespeed_admin { allow 127.0.0.1; deny all; }
location ~ ^/pagespeed_global_admin { allow 127.0.0.1; deny all; }

Not sure it’s an nginx issue since your other permalinks seem to work just fine. Try hitting the repair-button in Podlove > Support.
