Network error: Error: connect ETIMEDOUT 149.154.167.220:443 - node.js

Question

I have this code block in server.js file:
const Telegram = require('telegram-node-bot')
const tg = new Telegram.Telegram('***********token**************',{
workers:1
});
const pingController = require('./controllers/ping')
,otherwiseController = require('./controllers/otherwise')
tg.router.when(new Telegram.TextCommand('/ping','pingCommand'), new pingController())
.otherwise(new otherwiseController());
and this code block in ping.js file:
const Telegram = require('telegram-node-bot');
class pingController extends Telegram.TelegramBaseController{
pingHandler($){
$.sendMessage('pong');
}
get routes() {
return{
'pingCommand': 'pingHandler'
};
}
}
module.exports = pingController;
and finally this code block in otherwise file:
const Telegram = require('telegram-node-bot');
class otherwiseController extends Telegram.TelegramBaseController{
handler($){
$.sendMessage('Sorry!!!')
}
}
module.exports = otherwiseController;
when I run node server.js, I just got error like this:
[error]
Network error: Error: connect ETIMEDOUT 149.154.167.220:443
at Object._errnoException (util.js:1031:13)

at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1195:14) request TelegramApiRequest { _method: 'setWebhook', _params: {
url: '' }, _multipart: undefined }
Also, the telegram is filtered in our country!!!, and I use the Siphon 3 proxy.

Answer 1

its because you have't set your proxy for your terminal/cmd
for Linux:
export http_proxy='http://proxyserveraddress:3128'
export https_proxy='https://proxyserveraddress:3128'
for Wndows:
set HTTP_PROXY=http://proxyserveraddress:3128
set HTTPS_PROXY=https://proxyserveraddress:3128

Answer 2

You can use SOCKS5 proxy with the socks5-https-client lib. Example:
const TelegramBot = require('node-telegram-bot-api')
const Agent = require('socks5-https-client/lib/Agent')
const bot = new TelegramBot(process.env.TELEGRAM_API_TOKEN, {
polling: true,
request: {
agentClass: Agent,
agentOptions: {
socksHost: process.env.PROXY_SOCKS5_HOST,
socksPort: parseInt(process.env.PROXY_SOCKS5_PORT),
// If authorization is needed:
// socksUsername: process.env.PROXY_SOCKS5_USERNAME,
// socksPassword: process.env.PROXY_SOCKS5_PASSWORD
}
}
})
This solution to continue developing bot on your local PC (without proxy you can not start bots from Iran and Russia) and it works.
