Since June 5, 2026, Telegram is almost unusable in Russia. Official MTProto proxies (including built‑in Fake TLS) are fully blocked by DPI. Direct connections also fail. Issue affects all clients (Desktop, Android, iOS) on all major ISPs (Rostelecom, MTS, Beeline).
Symptoms: permanent "Connecting...", no media, no messages, calls drop. Changing IP/port/proxy provider does nothing.
Root cause: Russian DPI now analyzes TLS handshake fingerprints. Official client uses a static JA4 fingerprint in ClientHello. DPI recognises it and injects RST packets. Even Fake TLS is detected because client's TLS stack differs from real browsers.
Proof it's client‑side: community forks with dynamic JA4 rotation (e.g., telemt/tdlib-obf) work immediately with the same proxy and network. Local DPI tools (GoodbyeDPI, zapret) also help.
What doesn't work: any MTProto proxy, Telegram Premium proxy, SOCKS5, many VPNs.
Working workarounds: forked client with JA4 randomization, or local fragmentation tools (GoodbyeDPI/zapret/ByeDPI).
Why Telegram must fix: same network+proxy work with patched client. Official static fingerprint is a design weakness.
Request to developers:
Implement dynamic JA4 fingerprint randomization (random browser‑like ClientHello per connection). Community already did it.
Add packet fragmentation for initial handshake packets (inspired by GoodbyeDPI/zapret).
Full detailed description, including steps to reproduce, logs, and GitHub issue #30733, is attached as a screenshots.
Please prioritise this fix. Millions of Russian users are affected since June 5, 2026.
Thank you.
Steps to reproduce
Steps to reproduce (for developers)
Be in Russia with an ISP that implements TSPU DPI filtering.
Install the latest official Telegram Desktop client.
Obtain any working MTProto proxy (with or without Fake TLS).
Configure the proxy in Settings → Advanced → Connection Type.
Observe that the client remains in “Connecting…” indefinitely.
Capture traffic with Wireshark – you will see a TLS ClientHello with a static fingerprint, followed by a forged RST packet from the ISP.
Switch to a community forked client (e.g., the one linked in issue #30733) without changing the proxy or network – the connection works immediately.

This is critical for Russian users. Millions of people waiting for the fix to restore functionality of there MTProto proxy connections. Please, make Telegram alive again!

Telegram is now the only way for Russians to communicate with each other safely and to be aware of current events. Including information about airstrike threats, since usually there are no air raid sirens at all. Thus for some people, an uncensored information channel is literally vital. Fix the proxy for telegram, for God's sake.

This problem affects not only Telegram desktop, but also Android and iOS Telegram apps. Russians don't have the access to Telegram on all devices. Please, fix this as soon as possible. Telegram is the only way to communicate safely in Russia!

It's very disappointing that the Telegram team and Pavel Durov still haven't responded to the ongoing issue with Telegram in Russia.
If there are no plans to fix this problem, please just say so clearly: - Telegram is leaving Russia; - Fixing this issue is not a priority; - This problem cannot be solved, etc.
That way, Russian users would know not to wait for a solution and could look for alternatives: - Finding forked clients; - Switching to another messenger.
However, the recent mass promotion of 2‑year Premium subscriptions now looks like a last‑minute attempt to extract money from users before the service becomes unusable.
We just want to hear some kind of official response from the Telegram team and Pavel Durov.
