Thanks so much Maxim, can I send the 204 after a predefined timeout and
after a longer time the send_timeout?
Thanks

After send_timeout it’s already too late to return anything, as
nginx already tried to send the response to the client. If
send_timeout happens, the connection is closed.

Sorry, but I failed to understand the question.

As previously explained, you can’t send anything if send_timeout
is triggered - it’s already too late, as some response was already
send to the client.

Yes, but that’s not a trivial task when using vanilla nginx. For
example you can do this using the embedded perl module,
$r->sleep() command:

location / {
    perl 'sub {
        my $r = shift;
        $r->discard_request_body;

        sub next {
            my $r = shift;
            $r->status(204);
            $r->send_http_header;
        }

        $r->sleep(1000, \&next);
    }';
}

See Module ngx_http_perl_module for more details.

This can be also done using 3rd party modules. E.g., using the
delay module as available from
ngx_http_delay_module: log,
this can be done as follows:

location / {
    delay 2s;
    error_page 403 = /empty;
    deny all;
}

location = /empty {
    return 204;
}
