HTTP Status Code 463

[akmanocha]

Hi,

I am getting a strange error while using nginx as reverse proxy.

>From my upstream I get a response like in acess logs -

No logs in error logs- 

Could not find anything on net about status code 463
Looks like an issue with xforwarder has some issues? Why so many repeated
IPs? Has anybody else encountered the same issues?
