Caddy proxy connection refused

I have a problem with the reverse proxy, I set the backend and frontend to listen on port 3000 I use railway reverse proxy variables (2 photos) but it gives me an error that rejects the connection (3 photos) Project ID : 5da60841-1f6c-4e52-a848-3130a3b8ab8e

Solution:

1. remove the build and start commands you have set in the service settings. 2. https://github.com/brody192/create-react-app-starter - copy the nixpacks.toml and Caddyfile from this repo into yours....

In mi backend i use express:

   console.log("Server on");
  const port = Number(process.env.PORT) || 3000;

  return app.listen(port, "::", () => {
    console.log(`Server listening on [::]${port}`);
  });

   console.log("Server on");
  const port = Number(process.env.PORT) || 3000;

  return app.listen(port, "::", () => {
    console.log(`Server listening on [::]${port}`);
  });

in my frontend , i crete a domain and its working

Alejandro CapraOP•3mo ago

how can i fixed? Fun fact: I had to use in the packagejson in the backend "build": "rm -rf ./dist && tsc || true", and in the frontend "build": "react-scripts build || true", Why would the build stop if it had errors, even if my tsconfig was:

"compilerOptions": {
        "noEmitOnError":` false,

"compilerOptions": {
        "noEmitOnError":` false,

its a mono repo

When you are referencing something on the private network, you need the URL to be <internal domain>:port number so, for your example, your frontend_domain should be app-frontend.railway.internal:3000 and your caddy config should reference the variable

Alejandro CapraOP•3mo ago

This caddy repo asks you for it separately, I tried the older one that was like that and it doesn't work

Alejandro CapraOP•3mo ago

the caddy this is the repo https://github.com/railwayapp-templates/caddy-reverse-proxy

yep the template does ask for the domain and port as separate variables.

Brody•3mo ago

the issue here is that your frontend is not listening on ipv6.

Alejandro CapraOP•3mo ago
