如何让 python 代码通过电脑的网络而不是路由器，还请各位大神指教，不胜感激

电脑上梯之后，浏览器和很多软件都可以正常登陆外网，但是 python 代码不能正常登陆外网，而是通过路由器网络（我在路由器上梯之后可以正常运行代码），请问如何让代码经过电脑而不是经过路由器？
代码如下：

import yagmail# pip3 install yagmail

yag = yagmail.SMTP(user='woiwo****@gmail.com', password='********')
body = "邮件正文"
yag.send(to='frank****@gmail.com', subject='邮件主题', contents=['123'])
print("已发送")

下面是提示错误：

C:\Users\wohao\AppData\Local\Programs\Python\Python37\pythonw.exe C:/Users/wohao/OneDrive/INS/ins/tkinter/yagmail_test.py

电脑已经上梯了，是不是代码没有走电脑网络呢，请问如何才能解决？
我查询了很多网站，都是和爬虫有关的代理，解决不了这个问题，还请各位大神指教，不胜感激。
