title: How to set Telegram bot webhook?
body: <p>I'm developing a Telegram bot, and I want to set the webhook to my domain's URL. I've already generated a self-signed certificate following the <a href="https://core.telegram.org/bots/self-signed" rel="noreferrer">Telegram's guide</a>. However, I'm not able to set the webhook. I've searched previous answers and found <a href="https://stackoverflow.com/questions/33392278/upload-self-signed-ssl-certificate-to-telegram">this one</a>, but it doesn't work to me. Can anybody explain me how to upload the SSL certificate and set the webhook?</p>
