The project deployed successfully, however when we create a deployment url it shows 502 bad gateway.
What we have tried
create a port env in railway env's and add 8000
tried ports 8080, 8000, 3000 etc
our nuxt config file
// nuxt.config.ts

How to get a proper deployment url and Fix 502 bad gateway error?

Hey Shreyas, could you please check out our Nuxt guide and see if it helps https://docs.railway.com/guides/nuxt ?
Could you also ensure your application is binding to 0.0.0.0 and listening on the port specified by the PORT environment variable that Railway injects into your application. Railway assigns a dynamic port to your service, and your application needs to listen on that specific port.
You might need to modify your Nuxt configuration to respect the PORT variable provided by Railway. Instead of hardcoding a port in your nuxt.config.ts or elsewhere in your application, using the process.env.PORT variable like so could help:
// nuxt.config.ts
export default defineNuxtConfig({
server: {
host: '0.0.0.0', // Default: localhost
port: process.env.PORT || 3000 // Default: 3000
},
// other configurations...
});Could you make sure that your start script in package.json uses this configuration? Your existing start script looks good as it is already pointing to node .output/server/index.mjs, which should follow the configurations defined in your Nuxt setup.
Once you've made these changes, redeploy and check the detailed logs to see if there are any other underlying issues. Our docs on Application Failed to Respond are also really helpful in such cases. Hope this helps and let me know Let me know if you need any further assistance!

Hey, we have updated our nuxt configuration and added the port env, and we are following the railway guide as well, the error is still present
Deployment url shows 502 error (there are no errors in build/deployment process)
