Can't generate PDF in localhost

[DavidCasillasRivero]

I have two environments devel and prod. Both run under https but prod is a real live web application with a valid certificate and devel is run in localhost with a self signed certificate.

Testing with prod application works as expected but devel environment always loads an empty white screen and generates an empty one page pdf. I have tried with --ignore-certificate-error flag but the result is the same. Loading the URL in the browser works fine.

The cookie used is extracted from the browser after a succesful login using the same method in both prod and devel environments.

Here is the invocation command I use and debug information:
