I followed the excellent tutorial and the SSL cert verifies as valid. However the Drupal login to access the admin no longer activates and the page just reloads to itself. I enabled debug for the NGINX logs and below are the results. It ends with:

**recv() not ready (11: Resource temporarily unavailable). **

What’s odd is our dev Drupal site works just fine. When I compare the logs the only difference is that this appears in the dev site:

***4 http request line: "POST /user HTTP/1.1"**

Below are the verbose debug logs. Any suggestions?
