MTProxy worked for Android/Desktop but not iOS

[uponatime2019]

The same MTProto proxy instance works correctly on:

• Telegram for Android
• Telegram Desktop (Windows/macOS/Linux)

but does not work on Telegram for iOS. On iOS, the client stays on Connecting/Connected/Connecting/... without success to establish a connection.

The developers have completely abandoned MTProxy, yet they update their apps without notifications, which break the proxy. I'm starting to get disillusioned with Telegram...

I would prefer to support http+tls (https) / socks5+tls proxies, making it more universal.
