pymysql - 谷歌雲 - OperationalError：（2003，「無法連接到MySQL服務器上

Question

我的Python代碼非常簡單：

import pymysql as pymysql 
db = pymysql.connect(
      host='*.172', user="*one", passwd=CLOUDSQL_PASSWORD, 
    database='my_db_name') 

我已經創建了這裏的MySQL實例：

創建一個數據庫，在這裏：

而且gaveaccess這裏的用戶：

但我不斷收到以下錯誤：

---------------------------------------------------------------------------
