Request Denied

I get this error when I try and retrieve my reviews – and I’ve tried the manual entry of our location.

{
“error_message” : “This IP, site or mobile application is not authorized to use this API key. Request received from IP address 165.73.139.208, with referer: https://gwynne.graphics/”,
“html_attributions” : [],
“status” : “REQUEST_DENIED”
}

Any ideas?
Thanks
