Telegram proxy works on Wi-Fi but not on mobile data
A proxy that works at home and fails on mobile data, or works on 4G and fails at the office, shows that the two networks filter traffic differently. The proxy itself is fine: one network blocks it. The practical answer is to keep a working server for each network.
What you see
| Where | On screen |
|---|---|
| On Wi-Fi | Connected, with a ping |
| On mobile data | “Unavailable” or “Connecting to proxy…” |
What it usually means
- Each operator and provider blocks on its own schedule and with its own lists. A server already blocked on one network can still be open on another.
- Some networks only let common ports through, such as 443, and drop unusual ones.
- Office, school and public Wi-Fi often block everything except ordinary web browsing.
- Mobile operators sometimes enforce national bans more strictly than home providers. In Nepal, for example, mobile operators applied the Telegram ban while many fixed-line providers did not.
Check it step by step
- On the failing network, open the proxy list in Telegram and wait for the statuses.
If all servers fail there, the network blocks proxies broadly. If some pass, keep those for this network.
- Try a server on port 443.
Port 443 carries ordinary HTTPS, so strict networks rarely close it. The port is the number after the colon in the list below.
- Prefer FakeTLS servers, then dd.
They are harder for a network to recognise than plain ones. How the types differ.
- Save one working server for each network.
With Auto-switch proxies on Android or Telegram Desktop, the app moves on to another saved server when the current one stops working.
- If nothing passes on that network, use a VPN there.

Try a server that passed our last check
These servers passed a full MTProto handshake from our checker. List built 18 October 2026 at 16:31 UTC; it is rebuilt every 20 minutes. A server that works for our checker can still be blocked on your network.
- Of the 50 highest-ranked servers in our live list right now, 11 use port 443.
- On 9 October 2026, 17.5% of the 200 working proxies in our list used port 443. The most common port was 8443 (53.5%).
- FakeTLS made up just 5% of working proxies on that date, so these servers are scarce. What 200 working proxies look like.
Questions
Why would my operator block one proxy and not another?
Block lists are built from addresses that get noticed, usually popular public servers. Fresher or less shared servers can stay open longer.
Can a setting make the proxy work on mobile data?
No Telegram setting gets around a block. Changing to another server, ideally on port 443 with a FakeTLS secret, is the realistic option.
Does this mean my operator blocks Telegram?
Not necessarily. Test Telegram without the proxy on the same network. If it connects, the network blocks only that proxy, and you may not need one there.
