WSARecv() failed (10054: An existing connection was forcibly closed by the remote host) while reading response header from upstream

Posted by lzjyzq2 
Problem): I encountered this problem and prompted in the log: wsarecv() failed (10054: an existing connection was forcefully closed by the remote host) while reading response header from upstream.Please advice from the master for the solution, thank you.

Configuration): some of my configurations are as follows:

worker_ processes 2;
error_ log logs/error_ 2.log warn;
pid logs/nginx. pid;

events {

worker_ connections 1024;

}



http {

include mime. types;

resolver 8.8.8.8;

default_ type application/octet-stream;

rewrite_ log on;

access_ log logs/access_ 2.log main;

sendfile on;

underscores_ in_ headers on;

keepalive_ timeout 65;

... others

server{

... others

location /jd/ {

lua_ need_ request_ body on;

default_ type 'text/html';

error_ log logs/error_ 3.log warn;

lua_ code_ cache on;

rewrite_ by_ lua_ file cooperoplua/jumpserver. lua;

}



location @jump_ proxy {

proxy_ pass $uri;

proxy_ http_ version 1.1;

proxy_ set_ header Upgrade $http_ upgrade;

proxy_ set_ header Connection $connection_ upgrade;

# proxy_ set_ header Connection "upgrade";

# proxy_ set_ header Connection keep-alive;

proxy_ set_ header Host $host:$server_ port;

proxy_ set_ header X-Real-IP $remote_ addr;

proxy_ set_ header X-Forwarded-For $proxy_ add_ x_ forwarded_ for;

expires 0d;

}

}

}
Try):I've tried some methods, such as ` keepalive_ requests 500;`; Or "worker_connections: 4096;" And other methods. However, there is no effect, and the prompt is still: wsarecv() failed (10054: an existing connection was forcefully closed by the remote host) while reading response header from upstream, but only one host has a problem, the other hosts are good, and there is no problem on my local host.
This problem has been solved. I have removed the following two configurations:

proxy_ set_ header Host $host:$server_ port;

proxy_ set_ header X-Forwarded-For $ proxy_ add_ x_ forwarded_ for;
