Hey there! We've found the following might help you get unblocked faster:

• 🧵 errno: -3008, code: 'ENOTFOUND', #syscall: 'getaddrinfo', hostname: 'postgres.railway.internal'

• 🧵 Nextjs and node server not able to communicate over private networking

• 🧵 Suddenly can't connect privately using postgres.railway.internal

If you find the answer from one of these, please let us know by solving the thread!

https://docs.railway.com/guides/private-networking#node--next

For the server to talk via private networking, it should listen on IPv6. Specifically, for your nextJS application, you can update your start command to bind to both IPv4 and IPv6. (as prescribed in the documentation):

next start --hostname :: --port ${PORT-3000}

Change the port according to your needs & refer to the linked documentation page to get a better understanding of what needs to be done.

If that helps to resolve your issue, do mark this as the solution

Unfortunately, the error persists. It seems I can't access the database via private network during the project's build phase.

It is not available during the build process. I hope that answers your query
