Thanks for the very informative blog post; it was very helpful in getting my Nginx configuration up-to-date and working with Drupal 8. In the process, I discovered a couple more configuration changes that are also required in order for everything to work right. I described the applicable symptoms and their fixes in my blog post; some of these changes should also be applied to your Nginx template (c.f.  and ). The Drupal recipe in the Nginx documentation is now up-to-date for Drupal 8, including the fix from this blog. Thanks again for writing this up!
