How to connect webhook for Telegram bot?

Question

PHP

Hey!
There is a server with SSL, I try to make a request to install setWebhook, through var_dump it displays the answer:
{"ok":false,"error_code":400,"description":"Bad Request: bad webhook: getaddrinfo: Name or service not known"} bool(true)
What to do?

Answer 1

How exactly are you making the request? What are you sending?
