无法连接到主机api.telegram.org:443 SSL：默认值

Question

我正在在AIOGRAM框架上写电报机器人。当我运行它时，一切都很好，但是今天我遇到了错误，无法连接到主机api.telegram.org:443 ssl：default 我不知道有什么问题。
我正在使用ubuntu 20.04.2 lts
这是完整的错误

Answer 1

我认为您正在pythonanywhere上运行Python Telegram bot脚本。如果这是真的，请确保您在bot实例中集成了代理设置：

bot = Bot(token='YOUR API TOKEN GOES HERE', proxy='http://proxy.server:3128')

如果已经设置了该设置，并且您仍然会从Pythonanywhere中获得与TLS-In-In-TLS相关的错误：

1. 菜单选项上的Tap Consoles。
2. 关闭脚本正在运行的控制台。
3. 再次运行脚本。

Answer 2

您的基本URL应该是 https://api.telegram.org/ ，也就是说，在此期间看到 connection> connection> connection> connection>轮询。

但是，查看错误 socket.gaierror：[errno -3]名称分辨率的临时故障在获取主机的地址信息时存在问题。我将从排除任何连接问题开始，然后检查您的/etc/hosts 文件，以查看是否有任何构造。

如果两者都没有起作用，请尝试直接对API进行轮询，以查看问题是否仍然存在。

通常，设置网络钩比长期投票要好得多。
它需要一些设置，需要API和像Ngrok这样的反向代理，但是一旦启动并运行，与长时间的投票相比，它是一种非常麻烦而优雅的解决方案。我创建了一个用于Telegram Webhooks的POC，如果您想从长期的投票转换为Webhooks，这可能会有所帮助。

Answer 3

在WSL2上运行时，我遇到了错误。我通过编辑此文件修复了它：

/etc/resolv.conf

并添加两个名称服务器：

nameserver 8.8.8.8
nameserver 8.8.4.4
