本地爬虫一切正常，阿里云却超时报错。
是这样，写个一个签到的python程序，使用的是requests库。
在本地pycharm和vscode都做过测试，一切正常，软件也成功显示签到成功。
因为是签到，所以想挂载云服务器进行定时操作，可所有代码都完成了，没想到卡在挂载服务器几天时间！
我用的是阿里云的服务器，目标链接是：

这个是报错的信息，我一开始以为是代码的问题，但是后来只是用基础的get请求，也还是一样的超时之后报错！
1. 一开始我以为是的服务器IP原因，后来用了代理IP在服务器运行，也还是不行!!
2. 我服务器的其他定时项目都没有任何问题可以执行，链接换成别的就可以执行，就是这个链接他超时。
3. 我用朋友的阿里云服务器试了一下，也还是同样的问题。
4. 突破口：用腾讯云函数可以运行，前提是打开了“**固定公网出口 IP**”这个选项！！如果不开启，也是超时之后报错。
我想过或许阿里云也有相关的设置，但是我网络这块不是很懂，所以没有找到，也不是很明白打开这个选项的作用。
**问题总结**：爬虫程序本地运行正常，阿里云运行超时之后报错，其他链接却一切正常。利用腾讯云可以运行，前提是得开启“固定公网出口IP”，请问如何解决阿里云报错的问题，有没有大佬知道问题的所在。已经研究很久了，奈何知识面不行，求解呀！
