set origin as * app.use(cors({ origin: * , optionsSuccessStatus: 200, credentials: true })) don't forget to change origin when you are ready to deploy your frontend

Ok so then this is specifically a railway app issue then? ideally you should be setting your frontend url as the origin and not the * because thats crazy unsafe

app.use(
  cors({
    origin: [process.env.FRONTEND_URL],
    methods: ["GET", "POST", "PUT", "DELETE"],
    credentials: true,
  })
);

app.use(
  cors({
    origin: [process.env.FRONTEND_URL],
    methods: ["GET", "POST", "PUT", "DELETE"],
    credentials: true,
  })
);

That's CORS, nothing to do with railway itself, what about you open your own thread and we try to help you?
