Production build is listening on http://[::]:3000 instead of localhost:3000.

How can I fix it?

Hi @Sagar Kapoor. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- This issue is related to how Nuxt's production server is configured to listen for incoming connections. The [::] notation indicates that the server is listening on all available IPv6 addresses, which is actually the default behavior for better compatibility across different network configurations. To change this behavior and make your Nuxt production server listen specifically on localhost:3000, you can modify the host configuration. Here are a few ways to do this: 1. Using environment variables: You can set the HOST environment variable before starting your server:

   HOST=localhost node .output/server/index.mjs

   HOST=localhost node .output/server/index.mjs

This is based on the information from the Nuxt deployment documentation (https://nuxt.com/docs/getting-started/deployment#nodejs-server), which states that the server respects the NITRO_HOST or HOST environment variables. 2. In your nuxt.config.ts file: You can set the host in your Nuxt configuration file:

   export default defineNuxtConfig({
     devServer: {
       host: 'localhost'
     }
   })

   export default defineNuxtConfig({
     devServer: {
       host: 'localhost'
     }
   })

This is based on the Nuxt configuration documentation (https://nuxt.com/docs/api/nuxt-config#devserver). 3. If you're using Docker, you can set the environment variable in your Docker configuration:

   environment:
     HOST: localhost
     PORT: 3000

   environment:
     HOST: localhost
     PORT: 3000

This approach is mentioned in a Stack Overflow answer (https://stackoverflow.com/questions/77046323) about configuring Nuxt in Docker. By implementing one of these solutions, your Nuxt production server should listen on localhost:3000 instead of [::]:3000. Remember that limiting the server to only listen on localhost may prevent external connections, which might not be desirable in some production environments. Make sure this change aligns with your specific deployment requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Subtle difference I think. [::] is the default route which means anybody on the network could potentially access it. [::1] on the other hand is the localhost ipv6 address (loopback) where only the host machine can use it.
