Problem with Bedrock WordPress

We are having problems with H5P plugin on a Bedrock WordPress instalation. 

1. Install a Bedrock WordPress instalation, and install the plugin. Go to the H5P content editor. 

2. WordPress, WP 6.2.2

3. Happens both mobile and desktop

4. Any browser

5. H5P version 1.15.5

6. GET https://app/plugins/h5p/h5p-php-library/styles/h5p.css?ver=1.15.5 net::ERR_NAME_NOT_RESOLVED

Attached is a screenshot.

7. No PHP error

As I stated in the beginning, we are using Bedrock. It seems that the plugin is not taking into account the Bedrock file structure. 

What can we do to solve this issue?

Thanks a lot!
