Why do I not see a Map?

Hey,

i try to use Nomad World Map on my Website.
I already set up a API on the google console and have activated it.
The API is restricted to Geocoding API, Maps JavaScript API, Maps Elevation API, Directions API.
And using *.example.com/* and example.com/* (of course with my website url not example)

But after updating settings in the nomadworldmap plugin, I still see no map. Only a grey field with the red location pin.
I can not find places, if i try i get the error “ERROR”.

Does anyone has a Idea for that??
Thanks in advance.
Tajo
