Nginx上游过早关闭连接，同时从上游形式Node js rocky proxy读取响应头

Question

我有一个nginx和一个节点服务器，它作为java后端服务器之间的代理。我的nginx配置

server {
listen 80;

server_name peoplehum.dev www.peoplehum.dev;
#rewrite ^/(.*)/$ /$1 permanent;
charset utf-8;
keepalive_requests 100;
keepalive_timeout 100s;
gzip on;
gzip_http_version 1.1;
gzip_vary on;
gzip_comp_level 6;
gzip_proxied any;
gzip_buffers 16 8k;
gzip_disable "MSIE [1-6].(?!.*SV1)";
client_max_body_size 16M;

#include /etc/nginx/proxy_header.conf;
#include /etc/nginx/proxy_buffer.conf;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_http_version 1.1;
proxy_set_header HOST $host;

#X-Forwarded-Proto header gives the proxied server information about the schema of the original client request (whether it was an http or an https request).
proxy_set_header X-Forwarded-Proto $scheme;

#The X-Real-IP is set to the IP address of the client so that the proxy can correctly make decisions or log based on this information.
proxy_set_header X-Real-IP $remote_addr;

#The X-Forwarded-For header is a list containing the IP addresses of every server the client has been proxied through up to this point.
#In the example above, we set this to the $proxy_add_x_forwarded_for variable.
#This variable takes the value of the original X-Forwarded-For header retrieved from the client and adds the Nginx server's IP address to the end.
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

在这里，当我向nginx发送大体请求到我的节点代理服务器时，它会在从上游读取响应头时提供上游过早关闭的连接。

我在节点js上使用岩石代理 - > https://github.com/h2non/rocky代理。我已经搜索了很多，并尝试了大部分其他相关问题的答案，但没有成功。
