I have a problem with API.

I try get metadata from MW Metadata and i have a error:

{
    "readyState": 4,
    "responseText": "{n  "error": {n    "code": 403,n    "message": "Requests from referer https://example.com are blocked.",n    "errors": [n      {n        "message": "Requests from referer https://example.com are blocked.",n        "domain": "global",n        "reason": "forbidden"n      }n    ],n    "status": "PERMISSION_DENIED",n    "details": [n      {n        "@type": "type.googleapis.com/google.rpc.ErrorInfo",n        "reason": "API_KEY_HTTP_REFERRER_BLOCKED",n        "domain": "googleapis.com",n        "metadata": {n          "consumer": "projects/0000000000",n          "service": "youtube.googleapis.com"n        }n      }n    ]n  }n}n",
    "responseJSON": {
        "error": {
            "code": 403,
            "message": "Requests from referer hhttps://example.com are blocked.",
            "errors": [
                {
                    "message": "Requests from referer https://example.com are blocked.",
                    "domain": "global",
                    "reason": "forbidden"
                }
            ],
            "status": "PERMISSION_DENIED",
            "details": [
                {
                    "@type": "type.googleapis.com/google.rpc.ErrorInfo",
                    "reason": "API_KEY_HTTP_REFERRER_BLOCKED",
                    "domain": "googleapis.com",
                    "metadata": {
                        "consumer": "projects/639927084543",
                        "service": "youtube.googleapis.com"
                    }
                }
            ]
        }
    },
    "status": 403,
    "statusText": "error"
}

I tried to disable the API key restriction but that doesn’t do anything either. The help from another thread doesn’t work either.
