I'm trying to connect my servers with each other, but I keep getting 502 errors in NGINX or 301 redirects in Express.

I've tried using both public and private addresses, but the issue remains the same.

Note: https://httpbin.org/get is public and not mine

Note: It works fine in codespace

Here's my default.conf:

server {

listen 80;

server_name _;

location / {

proxy_pass https://httpbin.org/get; or http://d-account.railway.internal:8080;

}

}
