We had this working on another machine (Ubuntu 14, PHP5) and after migrating it the plugin no longer seems to work.
I checked the credentials and they worked fine via AWS CLI to add an invalidation. There doesn't seem to be anything useful in the apache error log. The GUI reports back "Your request contains one or more invalid invalidation paths."
I am thinking perhaps it could be the newer PHP7, a php module or something similar is missing, or something updated in Wordpress itself that made it stop working.
