Hello everyone,

I posted this to stack-exchange, but this is probably the better place to get a real answer. Long story short, I think we're hitting the SSL renegotiation problem described here: http://forum.nginx.org/read.php?2,258464,258464#msg-258464 Basically, we're trying to wrap a request made by an internal application over HTTP, into a HTTPS request to an upstream server that requires a client certificate. If I understand the post correctly, as part of that connection, the remote server asks for a client cert, which trips up NGINX b/c of the SSL renegotiate.

Config:

location /secure/api/ {
proxy_pass https://secure.webservice.com/secure/api/;
proxy_ssl_certificate /etc/ssl/api-client.crt;
proxy_ssl_certificate_key /etc/ssl/api-client.crt.key;
proxy_ssl_verify off;
}

We have logging turned up to debug but do not get the 'SSL Renegotiation disabled' message in the logs, which is why I'm posting here for confirmation.

error.log:

2015/08/25 15:33:56 [info] 29810#0: *57 client closed connection while waiting for request, client: x.x.x.x, server: 0.0.0.0:80
2015/08/25 15:34:05 [info] 29810#0: *53 epoll_wait() reported that client prematurely closed connection, so upstream connection is closed too while reading response header from upstream, client: x.x.x.x, server: our.proxy.com, request: "GET /secure/api/ HTTP/1.1", upstream: "https://y.y.y.y:443/secure/api/", host: "our.proxy.com"


Is there any workaround for this?

Thanks in advance.
