通过Mac上的终端将Python连接到LAN Ubuntu服务器上的MySql数据库不起作用

我正在尝试将Mac上的Python连接到在安装了Ubuntu Server LTS 20.04的RaspBerry Pi 4上运行的MysqL数据库中，这两台计算机都在我的LAN上。目前，我在Mac上具有MysqL Workbench，并且能够使用SSH通过标准TCP / IP连接访问数据库。通过终端通过SSH访问服务器或登录相关数据库都没有问题。

我在Mac上运行Python 3.8.5，在RPi4上安装的Ubuntu Server上运行最新版本的MysqL Server。

当我在Python文件中编写连接代码并尝试通过终端运行它时，问题就出现了。这是我遇到的错误（空格是我的）：

  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/MysqL/connector/connection_cext.py",line 216,in _open_connection

During handling of the above exception,another exception occurred:
