Same here (squid 3.2.0.14):
502 Bad Gateway
nginx/0.7.67
> It works without squid.
Same here, too.
> Does anyone know why?
Seems to be a malformed web site.
I've tested (without squid)
lynx www.allplanlernen.de/themen/impressum.html
and got the informations; looking with a browser (behind squid) onto the
side gets
Internal Error (check logs)
and that's an error message for the website administrator, not for me.
Viele Gruesse!
Helmut
