403 Error | API restrictions

I am having an issue using restrictions at the API level, If I set it to None I can get it to work, if I set it to use http restrictions ( with https://domain.name/* or without https:// ). I get an error message.

Is it not possible to use API restrictions for this plugin?

(403) The request did not specify any referer. Please ensure that the client is sending referer or use the API Console to remove the referer restrictions.

Please ensure that both your Google Calendar ID and API Key are valid and that the Google Calendar you want to display is public.

The calendar is public and works as expect if the restrictions are set to none.
