Please check the following issue in the Telegram Desktop repository: telegrammessenger/tdesktop/issues/30733. MTProto connections are now being detected via JA4 fingerprinting. This fingerprinting method allows censors to block Telegram traffic effectively. The protocol needs to be updated/obfuscated in the iOS client as well. Otherwise, users in Russia (and other censored regions) will completely lose physical access to the messenger.
