Using interactive video in local.

Hi,

I am using moodle inside docker, my aim is to be able to add an interactive video activity inside the course. Seems that the "create content" does not work if the adress is localhost, which is the case with docker. The message is:

Your site is having difficulties connecting to H5P.org and listing the available content types.

What I want, is a way allowing me to use to interactive video plugin without need to host any thing on H5P.org. Is there any way to solve this? 

Best regardds.
