问题遇到的现象和发生背景
非IT从业者，最近因为业务的需要，自己搭建数据库。
MySQL部署电脑A上，现在想在电脑B上用Python连接MySQL，结果报错了，这就是本次要向大家请教的问题。
另外，在电脑B上通过ssh和workbe nch是能连接上电脑A的MySQL的。
问题相关代码，请勿粘贴截图
pycharm中使用的连接MySQL代码如下：
import pymysql.cursors
connect = pymysql.Connect(
host='XXXX',
port=3306,
user='XXX',
passwd='XXX',
db='test',
charset='utf8'
)
运行结果及报错内容
报错pymysql.err.OperationalError: (2013, 'Lost connection to MySQL server during query') 。
详细报错信息见下：

我的解答思路和尝试过的方法
通过https://dev.mysql.com/doc/refman/5.7/en/error-lost-connection.html?%ra=link，核查了MySQL的配置如下，应该是没有问题的。
