You need to listen on the port that railway provides
more info:

const port = process.env.PORT || 4000

So its 3000 not 4000
Is it??

no, it's random

app.listen({ port: 4000 }, () =>
console.log(
🚀 Server ready at [http://localhost:4000${server.graphqlPath}](http://localhost:4000${server.graphqlPath}),
),
)
this is how , im passing the port no not in .env
