Installation and server related problems

I am trying to get H5P and Drupal 8 running in a dockerised environment. I have installed H5P and several of the libraries but during the content authoring process I press the 'save' button to submit the form and I get a white screen of death with an 'unexpected error' mesage. It appears as though the ajax callback is not working. When I check my server logs I get error messages such as the following. Does anyone have any ideas how I might solve this issue so I can author content?

Hi there, hope you can help me... I tried to integrate h5p into a fresh dupal-8.9.3 installation on a webserver. Unfortunately there is a failure when try to save the H5P-Settings because the Default h5p package path is not valid. There is only 'h5p' inserted into the field. It is such an directory inside the subfolder and the path which is show below the field is correct. Is there a solution for that issue?

We have moved from on-prem to the cloud and when a user goes to use their HP5 content link they are getting the following message when a prof tries to access their content

"Organization disabled
This organization account is currently disabled
Don't worry, we haven't deleted anything yet. Reach out to your administrator, or Joubel if you are the administrator, to get the account enabled again.

Has anyone seen this before, and if so, do you know what may be causing it? 

Thank you
