KivyMD with MYSQL : 现有连接被远程主机强行关闭

Question

昨天我用了我的应用程序，一切正常。昨天和今天我没有做任何更改，但现在我收到此错误：

我的所有图片博客帖子都出现此错误...（或者可能有 15/20 张图片）...

我正在使用 kivyMD 和 pymysql 连接到我的数据库。但是三个多星期以来一切都在昨天使用完全相同的代码运行。

我应该安装一些依赖项吗？

这里有一个 pip freeze :

certifi==2021.10.8
charset-normalizer==2.0.7
docutils==0.18
idna==3.3
Kivy==2.0.0
kivy-deps.angle==0.3.0
kivy-deps.glew==0.3.0
kivy-deps.gstreamer==0.3.2
kivy-deps.sdl2==0.3.1
Kivy-Garden==0.1.4
kivymd @ file:///C:/kivyLRF/KivyMD
Pillow==8.4.0
Pygments==2.10.0
PyMySQL==1.0.2
pypiwin32==223
pywin32==302
requests==2.26.0
urllib3==1.26.7

这里是我在 py 文件中导入的模块：

from kivy.lang import Builder
from kivymd.app import MDApp
from kivy.uix.screenmanager import Screen,ScreenManager
from kivymd.uix.list.list import ImageLeftWidget
import config
from kivymd.uix.list import IRightBodyTouch, OneLineAvatarIconListItem, ThreeLineAvatarListItem
from kivymd.uix.selectioncontrol import MDCheckbox
from kivy.properties import StringProperty
import functions
from kivymd.uix.tab import MDTabsBase
from kivymd.uix.floatlayout import MDFloatLayout
from kivy.core.window import Window
#Window.fullscreen = True

这是我的配置文件（但我知道这里没有问题...）：导入 pymysql.cursors

connexion = pymysql.connect(host='DATABASE ON OVH',
                         user='my user',
                         password='my password',                             
                         db='lrf',
                         charset='utf8mb4',
                         port=my port,
                         cursorclass=pymysql.cursors.DictCursor)
print ("connect successful!!")

我希望有人能帮助我。谢谢

所以，我不知道是什么、如何发生或为什么，但问题已经解决了。两个小时后，一切正常，再次运行...
