How to set up a Telegram Proxy (MTProxy)

This tutorial will teach you how to set up a Telegram MTProxy on an Ubuntu 22.04 sever using AWS Lightsail, although you can use any other Linux distribution and cloud provider.

Using a Telegram proxy is a safe, easy and effective way of overcoming Telegram bans. It's useful, for example, to keep using Telegram under tyrannical regimes, or to circumvent judges' decisions to block Telegram.

Telegram proxies are a built-in feature in all Telegram apps (both mobile and desktop). It allows Telegram users to connect to a proxy in just one or two clicks / taps.

Telegram proxies are safe: Telegram sends messages using their own MTProto secure protocol, and the proxy can only see encrypted traffic – there's no way for a proxy to decrypt the traffic and read the messages. The proxy does not even know which Telegram users are using the proxy, all the proxy sees is just a list of IPs.
