You open a chat to answer a message, and the word at the top of the screen stops you: "Connecting…". Underneath it, the conversation is a museum — the newest message is two hours old. The reply you type goes out with a small clock icon beside it, which is Telegram's quiet way of saying not sent, not delivered, just waiting. A voice note won't play. A photo sits there blurred. Nothing about the app looks broken, and that is exactly what makes this stall so maddening: Telegram hasn't crashed. It has lost its road to the server and is politely pretending otherwise.
Unlike most apps, Telegram holds one constant connection open to its servers and pushes everything through it. When that single link dies and fails to renegotiate, the whole app freezes in place at once — sending, receiving, calls, media, all of it. The causes are few and specific, and the most common one is a setting almost nobody knows Telegram has. Start there.
Quick Answer: Start where most guides never look: Telegram's own built-in proxy (☰ → Settings → Data and Storage → Proxy). If Use proxy is switched on and that server has died, Telegram will sit on "Connecting…" indefinitely — turn it off, or replace it with a working one. Next, force-stop Telegram so its stuck connection service restarts cleanly, and set Telegram's battery usage to Unrestricted so Android stops cutting the link while the app is in the background.
Fix 1: Check the Proxy Hiding Inside Telegram
Telegram has its own proxy settings, completely separate from your phone's VPN. If a proxy was switched on at some point — by you, by a setup guide you followed, by an old configuration — and that proxy server has since gone offline, Telegram routes every connection attempt into a dead end. No other app is affected, which is why everything else on your phone works while Telegram alone spins.
- Open Telegram and tap the hamburger menu (☰), then Settings.
- Open Data and Storage and scroll to the bottom, to Proxy.
- Tap Proxy settings. If Use proxy is on, turn it off.
- Return to your chats and watch the status line — it should flip to Online within seconds.
- While you're checking routes, also disconnect any phone-wide VPN app for the test (Settings → Network & internet → VPN) — a dead VPN produces the identical symptom.
One honest exception: in regions where Telegram is restricted, a proxy may be the only way in. In that case don't switch it off — replace it. A dead proxy is worse than none at all, so get a fresh, working server address from whoever provided yours and enter that instead.
Fix 2: Force-Stop Telegram So It Negotiates a Fresh Connection
Swiping Telegram away from your recent-apps list does not restart it. The connection runs as a background service, and that service can get stuck holding a session the server has already forgotten — it keeps "retrying" a handshake that will never complete. A force stop kills the service outright, so the next launch negotiates a brand-new connection:
- Go to Settings → Apps → See all apps → Telegram.
- Tap Force stop and confirm.
- Wait about ten seconds, then reopen Telegram.
- Watch the top of the chat list: "Connecting…" should give way to your chats syncing within a few seconds.
A close cousin of this stall is a status that reads "Updating…" instead. That one means Telegram is connected but its sync is backed up. The same force stop applies — afterwards, leave the app open on a stable connection for a minute and let it catch up.
Fix 3: Stop Android From Cutting Telegram's Connection
Learn to recognise this fingerprint: Telegram works perfectly while you're looking at it, then drops to "Connecting…" an hour or two after you put the phone down. That is battery management doing its job too aggressively. Telegram's connection lives in the background, and when the system puts the app to sleep, the link dies with it.
- Go to Settings → Apps → Telegram → Battery and select Unrestricted.
- On Samsung (One UI), also add Telegram to Settings → Battery and device care → Battery → Background usage limits → Never sleeping apps.
- On Xiaomi (HyperOS), open Settings → Apps → Manage apps → Telegram, switch Autostart on, and set its battery saver to No restrictions.
- If you use Data Saver, confirm Telegram is exempt: App info → Mobile data → allow background data (and unrestricted data use, if the toggle is offered).
Fix 4: Change Networks and Read What Happens
This one-minute experiment cuts the problem in half. Turn Wi-Fi off and open Telegram on mobile data — or, if you're already on data, join a Wi-Fi network:
- Connects on one network, not the other: the failing network is the problem. On home Wi-Fi, restart the router. On hotel, office, or campus Wi-Fi, open a browser and finish the sign-in page — Telegram cannot get through an incomplete captive portal.
- Connects on neither: toggle Airplane mode on for ten seconds, then off, to force the phone to re-register on the network, and try again.
The result tells you where to spend your time. A network-specific failure is never solved by reinstalling the app, and an everywhere failure is never solved by rebooting the router.
Fix 5: Empty Telegram's Cache — From Inside Telegram
Telegram's cache is every photo, video, and voice note it has downloaded, and on an active account it quietly grows to gigabytes. Corrupted entries in that store can jam the app's startup and connection sequence. Clear it the way Telegram intends, from inside the app:
- In Telegram: ☰ → Settings → Data and Storage → Storage usage → Clear cache.
- Then clear the system-level cache too: Settings → Apps → Telegram → Storage → Clear cache.
- Reopen Telegram and let media re-download as you scroll.
Your chats are safe: Telegram stores conversations in its cloud, so clearing the cache removes only downloaded media, and you stay signed in. Keep your finger off Clear data in the system settings, though — that signs you out, and signing back in means a verification code, plus your two-step verification password if you set one.
Fix 6: Update Telegram, or Reinstall It Clean
Telegram occasionally changes things server-side, and older builds can lose the ability to connect at all. Open the Play Store, search for Telegram, and install any pending update. If you're already current and the stall survives every fix above, uninstall Telegram and install it fresh — this replaces any corrupted app files that cache clearing can't reach. Your cloud chats, groups, and channels sync back when you log in with your phone number.
Before you uninstall, one warning worth reading twice: secret chats live only on this device. They are not in the cloud, and a reinstall deletes them permanently. Copy anything important out of them first — and make sure you can receive the login code (by SMS or another signed-in device) before you remove the app.
When the Server Is the One That's Down
If none of the six fixes moved the needle, consider that the problem may not be in your hands at all. Telegram's servers do go down, and when they do, every phone in the affected region shows the same frozen status. Confirm it before changing anything else: check a status site such as Downdetector for a spike in Telegram reports, try Telegram Web on a computer, or ask someone on a completely different network whether theirs works. If all of them are stuck, the only fix is waiting — these outages usually clear within a few hours.
One last quiet cause while you wait: a phone clock that has drifted breaks the encrypted handshake Telegram uses to connect. Go to Settings → System → Date & time and switch on Set time automatically. Menu names vary slightly by brand across Samsung, Pixel, and Xiaomi phones. Covers Android 10 through 14.

Straight Answers About the "Connecting…" Stall
Why does Telegram connect on mobile data but never on my Wi-Fi?
Because something on that Wi-Fi path is blocking Telegram specifically: a router firewall rule, an unfinished captive-portal login on a public network, or provider-level filtering of Telegram's servers. The practical workaround is Telegram's built-in proxy (Fix 1) with a working server, or simply using the network that lets it through.
Will clearing Telegram's cache delete my chats?
No. Your chats, groups, and channels live in Telegram's cloud and are untouched; the cache holds only downloaded media, which fetches again when you open a conversation. Even secret chats survive a cache clear — they are lost only if you clear the app's data or uninstall it.
Why does Telegram work when I open it, then drop to "Connecting…" later?
That pattern is battery management killing Telegram's background connection while the phone sits idle. Set Telegram's battery usage to Unrestricted (Fix 3) — on Samsung and Xiaomi phones this is the single most common reason for the recurring version of this problem.
