You open Telegram. The gray cloud icon appears. Messages won't send. Videos won't load. If you live in Iran, Russia, or China, this is a familiar frustration. Telegram is actively blocked by governments using deep packet inspection (DPI) and IP blacklisting. A regular VPN might help, but not always — especially when the VPN itself is targeted. There's a lighter, more Telegram-specific solution: MTProto proxies.
This guide explains why Telegram gets blocked, how MTProto differs from a VPN, and exactly how to set up a working proxy on your phone or desktop. No fluff, no jargon. Just steps that work.
Why Telegram Is Blocked
Governments block Telegram for the same reason people use it: encrypted communication that's hard to intercept.
- Iran blocks Telegram after protests, using DPI to detect the protocol and kill connections.
- Russia tried to block Telegram in 2018, and while the ban is technically still active, they rely on IP blocking and bandwidth throttling.
- China blocks Telegram entirely — the Great Firewall identifies and drops traffic by IP and protocol fingerprint.
The result: Telegram either doesn't connect at all, or connects only during off-peak hours when DPI systems are less aggressive.
What Is MTProto?
MTProto is Telegram's own encryption protocol. An MTProto proxy sits between your device and Telegram's servers. It wraps your Telegram traffic in a way that DPI systems can't easily recognize — especially if the proxy supports Fake-TLS, which makes the connection look like ordinary HTTPS web traffic.
When you connect through an MTProto proxy, your ISP sees only encrypted traffic to a random server, not to Telegram's IPs. The proxy doesn't decrypt your messages; it just forwards the encrypted packets.
MTProto vs VPN: The Real Differences
| Feature | MTProto Proxy | VPN |
|---|---|---|
| What it protects | Only Telegram | All apps and web traffic |
| Speed | Very fast (single protocol) | Slower (encrypts everything) |
| Battery drain | Minimal | Higher on mobile |
| Setup | One tap in Telegram app | Requires separate app and config |
| Detection by DPI | Lower if using Fake-TLS | Increasingly blocked |
When to use MTProto: If you only need Telegram and want the lowest overhead.
When to use a VPN: If you need to access other blocked services or want full anonymity.
For most users in censored regions, a combination works: keep a VPN for browsing, and use an MTProto proxy inside Telegram for reliable chat.
Step-by-Step Setup
Find a Working Proxy
You need a proxy in the format server:port:secret. A reliable source is the free-mtproto-proxies repository — it scrapes and publishes working proxies with Fake-TLS support, updated every few hours. You can also find them via Telegram bots, but the repo gives you a live web listing you can copy from.
Example proxy string:
45.67.89.12:443:ee2233445566778899aabbccddeeff0011223344
Android
- Open Telegram settings (bottom right → gear icon).
- Tap Data and Storage → Proxy Settings.
- Tap Add Proxy.
- Choose MTProto.
- Enter the Server, Port, and Secret from your proxy.
- Tap the checkmark to save, then toggle the proxy On.
- The cloud icon should turn green.
iOS (iPhone/iPad)
- Open Telegram settings (bottom right → gear).
- Tap Data and Storage → Proxy.
- Tap Add Proxy.
- Choose MTProto.
- Enter server, port, and secret.
- Save and enable the proxy.
- Verify the cloud icon shows green.
Desktop (Windows/macOS/Linux)
- Open Telegram Desktop.
- Click the hamburger menu (three lines) → Settings.
- Go to Advanced → Connection Type → Proxy Settings.
- Choose Use custom proxy → MTProto.
- Fill in server, port, and secret.
- Click Save. The connection should restore immediately.
You can also use a tg:// link. If your proxy is formatted as:
tg://proxy?server=45.67.89.12&port=443&secret=ee2233445566778899aabbccddeeff0011223344
Clicking it on your phone will open Telegram and auto-add the proxy.
Troubleshooting Tips
- Proxy works for a few minutes, then dies. DPI can temporarily block a specific IP. Switch to another proxy from the list. The free-mtproto-proxies repo updates frequently for this reason.
- Green cloud icon, but messages still slow. The proxy might be overloaded. Try one with lower ping (latency). The repo often shows ping times.
-
Cannot connect at all. Check that your secret is correct. For Fake-TLS, the secret must start with
eeor contain a hex string. Invalid secrets get silently dropped. -
Still blocked? Some regions block Telegram at the DNS level. Change your DNS to
1.1.1.1(Cloudflare) or8.8.8.8(Google) in your device settings. - Desktop proxy doesn't apply to calls. Telegram voice/video calls use a separate connection. If calls fail, you may need a VPN for those.
Security Considerations
An MTProto proxy can see your IP address and the fact that you're using Telegram, but not your message content — that's end-to-end encrypted in secret chats and server-client encrypted in regular chats. Still, you're trusting the proxy operator not to log metadata. For a deeper dive into what an MTProto proxy operator can actually see, a previous article covers this in detail: Understanding What an MTProto Proxy Operator Can Actually See.
If you want to minimize trust, use proxies that are known to be run by reputable sources. The free-mtproto-proxies repo lists proxies scraped from public channels; treat them as you would any free service — not for sensitive chats.
Keep a Few Proxies Handy
Proxies die. Governments adapt. The best practice is to save 2–3 proxies in your Telegram settings at all times. When one stops working, switch to the next. And if you ever need a fresh batch, the free-mtproto-proxies GitHub repository is a reliable, automated source — updated daily with live-working proxies.

Final Note
Telegram won't become unblocked anytime soon in these regions. But proxies make it usable. Stick with MTProto for speed, keep a tested list, and never assume a proxy is permanent. Bookmark the repo, check it when your connection drops, and you'll almost always have a green icon within a minute.
