In prod build, all pages (except /) return 404 when server rendered

When I test a prod build (next build and next start), server generated sub-pages return 404. This is reproducible with the next-routes example in the next repo - https://github.com/zeit/next.js/tree/master/examples/with-next-routes.

Steps to reproduce:

1. Follow installation instructions (https://github.com/zeit/next.js/tree/master/examples/with-next-routes)
2. Run commands next build followed by next start
3. Navigate to the first link Blog: Hello world
4. Refresh page and observe 404

I’m assuming this was working at some point. Maybe this was introduced in Next.js v3?

Yes, you can see this in the example’s package.json. The build script runs NODE_ENV=production node server.js.

Oh man, thank you so much. Was wrangling with this one for a minute and driving myself nuts…Realized I had a wonky ecosystem.config.js using npm run start instead of yarn start
