I'm getting weird 502 error while trying to fetch npm package inside of google service instance.
Error is constantly repeating on Google App Engine (Docker container deployment procedure), and Google Compute Engine instance (while trying to simple GET with curl or wget).
- yesterday all works fine, nothing changed in configs
- error happened on both urls: [http/https]://registry.npmjs.org
- can't get only .gz files and only from registry, plain html page (like registry main page) returns "200 OK" status
Here is log: http://pastebin.com/wGZ50Qrz
