我们正试图建立一个 SQL-Server->Debezium->Kafka Connect->Kafka Pipeline sql server（mssql）中几个表的设置
启动安装程序时，出现以下错误：日志：

{
  "name": "mssql-server-uat",
  "connector": {
    "state": "RUNNING",
    "worker_id": "172.17.0.3:8083"
  },
  "tasks": [
    {
      "id": 0,
      "state": "FAILED",
      "worker_id": "172.17.0.3:8083",
      "trace": <separately given below>
    }
  ],
  "type": "source"
}

跟踪：

可能的原因是什么？因为sql server正常运行，这很奇怪
如有需要，对问题进行评论以获取任何特定信息
编辑：此错误不会一直阻止连接。启动时，连接工作，cdc事件流式传输到kafka，甚至由我们编写的kafka使用者读取，但突然超时，出现上述错误。
