Debezium Connector - Communication link failure

Question

i got issue when connect local mysql using docker

{"error_code":400,"message":"Connector configuration is invalid and contains the following 1 error(s):\nUnable to connect: Communications link failure\n\nThe last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.\nYou can also find the above list of errors at the endpoint /connector-plugins/{connectorType}/config/validate"}

here my configuration :

 {
  "name": "inventory-connector",
  "config": {
    "connector.class": "io.debezium.connector.mysql.MySqlConnector",
    "tasks.max": "1",
    "database.hostname": "mysql",
    "database.port": "3306",
    "database.user": "debezium",
    "database.password": "dbz",
    "database.server.id": "184054",
    "database.server.name": "dbserver1",
    "database.include.list": "inventory",
    "database.allowPublicKeyRetrieval":"true",
    "database.history.kafka.bootstrap.servers": "kafka:9092",
    "database.history.kafka.topic": "schema-changes.inventory"
  }
}
