flask支持https失败了

Question

问题遇到的现象和发生背景

微信小程序开发，接口需要是https的备案域名。
域名已经申请好，icp备案也做完了。
我是用python flask搭的系统，之前是http的。
卡在https 了， 找了几个教程 ，没弄出来，求手把手解决

服务器：阿里云centos 8.1
python 3.8.3
flask:1.1.2

问题相关代码，请勿粘贴截图

注释中是尝试过的代码，没成功

if __name__ == '__main__':
    # app.run(host='0.0.0.0', port=8080, debug=True, ssl_context=('guidaonongye.com_ca.crt', 'guidaonongye.com.key'))
    app.run(host='0.0.0.0', port=8080, debug=True)

运行结果及报错内容

我的解答思路和尝试过的方法

这个是站长之家的证书
https://www.bilibili.com/video/BV1P3411h7je?spm_id_from=333.880.my_history.page.click

阿里云的证书也试过，没成功

我想要达到的结果

微信小程序可正常使用该接口

Answer 1

最后需要达到的结果就是微信小程序可以通过https调用这个接口是吧？
可以试一下看下
