Question

I am writing a telegram bot on the aiogram framework. Everything was good when I run it, but today I am getting error,Cannot connect to host api.telegram.org:443 ssl:default I do not know what s problem.
I am using Ubuntu 20.04.2 LTS
Here is the full error

The above exception was the direct cause of the following exception:

Answer 1

我假定,你是在斯堪的阿尼处驾驶你的斯堪达克的机器人。如果情况确实如此,则确保把代理机构并入机器人:

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

如果已经设立,你仍然从Adhur Any处获得与TLS-in-TLS有关的错误:

Tap consoles on the Menu option.
Close the console in which your script is running.
Run the script again.

但是,考虑到以下错误:<代码>socket.gaierror: [Errno -3] 代表第/etc/hosts文档,看看是否存在任何错误配置。

如果两者都没有奏效,则直接尝试投票,看看问题是否仍然存在。

In general, setting up webhooks are much better than long polling. It takes a bit of a setup, requires an API and a reverse proxy like ngrok, but once it is up and running, it is a very hassle free and elegant solution compared to long polling. I created a POC for telegram webhooks, which might be of help if you re looking to switch from long polling to webhooks.
