Website and Piwik on same server produces 403 - nginx

Question

i've got a site on xyz.com and piwik on xyz.com/piwik. Piwik is running fine, but unfortunately not all data - requested by piwik - are handled by the server.
I've watched behaviour like:
xyz.com/piwik/ -> error
xyz.com/piwik/index.php -> is fine
xyz.com/piwik/?module=... -> error

You are missing any default action for the /piwik/ URI. Presumably, if no other matching file is found, you would like the /piwik/index.php URI to be tried. Add a try_files directive to the outer location block, for example:
location /piwik/ {
try_files $uri /piwik/index.php$is_args$args;
location ~ /piwik/(.*\.php)(/.*)?$ { ... }
}
