Tornado, Nginx, Apache, ab - apr_socket_recv: Connection reset by peer (104)

Ich bin mit nginx und tornado auf c1.mittlere Instanzen.

Wenn ich laufen ab die unten ist meine Ausgabe. Nginx wird nicht funktionieren. Ich habe versucht zu tweaken der config-Datei für ninx ohne Erfolg. Wenn ich nur auf einem port durch die übergabe nginx z.B. `

  http://127.0.0.1:8050/pixel?tt=ff` 

dann seinen schnellen. Siehe ganz unten. Das muss ein nginx Problem, so wie ich Sie beheben? Auch unten ist die conf-Datei für nginx.
