comet http长链接场景下, nginx启用反向代理情况下 /sub报502 Bad Gateway

韩哥，你好，在comet http长链接场景下, nginx启用反向代理情况下, htt://testkf.xxx.com:9527/sub  firefox浏览器报502 Bad Gateway  会是什么原因

下面两个正常,能正常返回json格式结果，运行的代码是案例：/matyhtf/php-webim
htt://testkf.xxx.com:9527/connect
htt://testkf.xxx.com:9527/pub

upstream proxy_comet {
	server 127.0.0.1:9503 weight=1 max_fails=1 fail_timeout=1;
	#server 192.168.71.110:9503 weight=1 max_fails=1 fail_timeout=2;
	#server 192.168.71.130:9503 weight=1 max_fails=1 fail_timeout=2;
}
server {
    listen      9527;
    server_name testim.swoole.com;
    location / {
        proxy_pass htt://proxy_comet;
        #proxy_redirect  off;
		proxy_set_header Connection "keep-alive";
		proxy_send_timeout 1800;
		proxy_read_timeout 1800;
		proxy_connect_timeout 1800;
		keepalive_timeout 1800;
    }
}

/var/log/nginx/error.log
2016/04/07 08:44:13 [error] 17212#0: *25 upstream prematurely closed connection while reading response header from upstream, client: 192.168.137.1, server: testkf.xxx.com, request: "POST /sub HTTP/1.1", upstream: "http://127.0.0.1:9503/sub", host: "testkf.xxx.com:9527", referrer: "http://testkf.xxx.com/dialog.html"

弄了很久，还是找不到问题所在，/sub  长轮循在反向代理中存在问题，求指教。
