proxy_protocol - access server directly

[Jeff Dyke]

i have configured haproxy 1.6 and nginx 1.10.1 and all is well, but i'd
like to be able to access the servers directly on occasion and not through
haproxy.  Mainly this is done for troubleshooting or viewing a release
before it goes out to the public (its off the LB at the time).

Unfortunately accessing the server directly gives me a 400 and the logs
show Broken Header error messages. Is there a way around this without
removing proxy_protocol from the vhost configuration?

Thanks

minimal config:
server {
  listen 443 ssl http2 default_server proxy_protocol;
  // other stuff
  set_real_ip_from XXX.XXX.XX.XX;
  set_real_ip_from NNN.NNN.NNN.NNN;
  real_ip_header proxy_protocol;
  // more stuff
}

Example error.log entry
VX�www.example.com#" while reading PROXY protocol, client: YY.YY.YY.YY,
server: 0.0.0.0:8000
2016/08/11 11:25:28 [error] 23818#23818: *1445 broken header: "illegible
characters"


Thanks,
Jeff
