Question
Drupal 7 login does not work on NGINX after enabling SSL with Letsencrypt

Asked by RobbieTheK
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?

It would be great to know some more details about your Nginx and Drupal configurations. For what it’s worth, I was able to successfully configure SSL on a Drupal 8 site following the same Let’s Encrypt tutorial.
One thing to check on with Drupal 7 is the value of the
$conf['https']setting in yoursites/default/settings.phpfile. The Let’s Encrypt tutorial sets up a redirect from HTTP to HTTPS. Counterintuitively, for$conf['https']HTTPS-only sites the should be set toFALSEI’d also check to make sure that any plugins you might have do not need any special configuration for working with SSL.For more information on configuring HTTPS for Drupal, check out this article in their knowledge base.
