H5P Plugin for Pressbooks

I am unable to get the h5p plugin to work for my institutions Pressbooks account, which we have through SUNYConnect / Reclaim Domain. 
 The plugin is activated, but I am unable to upload anything useful or access any basic library. 

I was able copy an enter Pressbook which included H5P activities successfully, but this still did not activate my ability to add H5P content or access the library.

Has anyone seen this type of thing before. Reclaim Domain's Help Desk has not been able to help.
