I need help figuring out what is causing a 400 HTTP status code returned by Nginx when my Phoenix app is deployed with distillery. I recently upgraded Phoenix to 1.4 from 1.3.
None of the pages load and Nginx just returns 400.
There is nothing in the (distillery) logs and the app doesn’t crash.
When I attach to the running instance, the console (iex) doesn’t output anything when I try to load the page.
Is there a way to get the app to output something that would indicate where/why it fails?
