Xdebug not working with PHP-FPM and nginx

I have a fully working Xdebug in step debugger mode with Apache on Linux.

However, I need to get PhpStorm working with nginx.

My nginx server is fully working with PHP.

The step debugger is confirmed as working with xdebug_info(), i.e. the “Step Debugger” is enabled.

I have listening for “PHP Debug Connections” enabled in PhpStorm.

These are the Xdebug logs on the server when I load a page with PhpStorm listening for debug connections:

Thing is, it's almost the same log as an Apache setup.

However, step debugging is not working in PhpStorm.

Does anyone have Xdebug working with an nginx setup?
