I've deployed several Next.js applications on Railway, but I recently encountered this odd behavior with Response.redirect. Strangely, it redirects to localhost instead of the configured domain. I'm wondering if this issue is related to the latest Next.js update or perhaps with the Railway Edge Proxy.
I created a clean new Next.js app for testing, and the problem persists. However, when I deployed it to other platform like Vercel, the issue disappeared.

Vercel will strip localhost or replace it with your app's public domain.
Railway will not monkey patch your app, Railway will only ever run it as-is.
You will need to tell your code to either use the public domain or strip localhost yourself.
This would not have anything to do with the Railway platform.
