Question

I am trying to do a reverse proxy setup using

nginx (and caddy — doesn't matter which one)

environment: ubuntu 18.4.3 — Docker (docker-compose)
errors: connection reset by peer — Connection refused

when I link nginx/caddy to the container that I want to reverse proxy I get Connection refused

and when I use network_mode:host I get connection reset by peer

doesn't matter if it's nginx or caddy I get the same error.

nginx configurations:

upstream v2ray {
server 127.0.0.1:1080;
}

location /downloadstream {
proxy_pass http://v2ray;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_intercept_errors on;
if ($http_upgrade = "websocket" ) {
proxy_pass http://v2ray;
}
}

Caddyfile:

0.0.0.0:443

errors stdout

tls /root/certs/fullchain.pem /root/certs/privkey.pem

proxy /downloadstream 127.0.0.1:1080 {
websocket
header_upstream -Origin
}

something on the host environment must've been causing this. but I have no clue. can someone give me a hint?
