1. Telegram Login Errors
Common Login Problems:
- “You cannot log in via SMS.”
- Telegram not sending security code.
- Phone number not recognized.
- Login loop or “Too many attempts” warning.
Causes:
- Unstable internet connection.
- Outdated app version.
- Cache or server sync issue.
- SIM verification blocked temporarily.
Fixes:
Step 1: Check Connection
Ensure mobile data or Wi-Fi is stable. Try switching between them.
Step 2: Update or Reinstall Telegram
- Open the Play Store / App Store → Search Telegram → Tap Update.
- If already updated, uninstall and reinstall.
Step 3: Use Alternative Login Method
- Use Telegram Desktop/Web to log in with a QR code.
- Open desktop → Click “Login by QR code.”
- Scan with your mobile Telegram app → instant login.
Step 4: Clear Cache
- Android → Settings > Apps > Telegram > Storage > Clear Cache.
- iPhone → Settings > Telegram > Storage Usage > Clear All Cache.
Step 5: Wait and Retry
Repeated login attempts may trigger cooldown limits. Wait 15–30 minutes.
Pro Tip: Telegram sends login codes to active devices as well. Check your previous Telegram session — the code might appear there instead of SMS.
2. Notification Issues on Telegram
Missed messages? Silent groups? These are among the most annoying Telegram errors — thankfully, every cause has a fix.
Typical Notification Problems:
- “Telegram notifications not working.”
- Notification sound missing.
- Delayed or silent alerts.
Fixes by Device:
Android
- Open Phone Settings → Apps → Telegram → Notifications.
- Make sure all toggles are ON, especially “Allow Sound” and “Pop‑up Notifications.”
- Disable Battery Optimization:
- Settings → Battery → Telegram → No Restrictions.
iPhone
- Go to Settings → Notifications → Telegram.
- Toggle on Allow Notifications and Sounds.
- Inside Telegram app: Settings → Notifications → Enable Private Chats, Groups, and Channels.
Desktop
- Click Settings ⚙️ → Notifications and Sounds.
- Activate Desktop Notifications + “Play Sound.”
- Ensure Focus Assist (Night Mode on Windows) isn’t muting alerts.
Quick Restart Trick: After changing notification settings, restart your phone once. It forces Telegram to re‑register for background alerts.
3. Telegram Update Problems
Sometimes Telegram won’t update automatically or gets stuck mid‑installation — another common Telegram error in 2025.
Problems Observed:
- Update not appearing in Play Store / App Store.
- “Installation failed” warning.
- Telegram Desktop asking for manual installation.
Fixes:
Mobile (Play Store / App Store)
- Clear store cache (Android Only):
Play Store > Settings > Storage > Clear Cache. - Ensure your device has 1 GB minimum free space.
- Restart your phone, then re‑check store updates.
Desktop (App Installer)
- Visit telegram.org → download latest Windows or Mac version.
- Close older Telegram processes from Task Manager.
- Reinstall over existing version — no chat data lost (cloud‑stored).
4. Telegram Not Opening or Freezing
When Telegram suddenly freezes or closes, multiple background factors may cause it:
Possible Causes:
- Device RAM overload.
- Corrupted cache files.
- Temporary server downtime from Telegram Cloud.
Quick Fix:
- Close and reopen app.
- Restart device.
- Clear cache (Storage > Clear Cache).
- For Android users: Long press Telegram icon → App info → Force Stop → Reopen.

5. Sync or Message Delay Error
Delayed messages or missing images are also part of ongoing Telegram errors in slow connection zones.
Fix Steps:
- Switch to Wi‑Fi if on mobile data.
- Disable Data Saver / Battery Saver.
- Inside Telegram → Settings > Data and Storage > Set “Download Automatically.”
- For desktop: Check proxy settings → disable VPN if unstable.
6. Verification & SMS Code Not Received
If Telegram’s code is missing from SMS or call, try these fixes:
- Confirm phone number with correct country code.
- Switch to “Login via call” if SMS fails.
- Check for network signal and roaming mode.
- If SIM is inactive, use QR code login on Telegram Web.
Codes expire in two minutes. Avoid multiple requests — it may lock your account temporarily.
7. Telegram Notification “Not Showing on Lock Screen”
- Android > Settings > Lock Screen > Notifications > Enable for Telegram.
- iOS > Settings > Notifications > Telegram > Show Previews → Always.
If you’re still notified but sound silent, restore notification tones:
- In Telegram open Settings > Notifications and Sounds.
- Pick custom ringtones for specific chats.
8. Telegram “Connecting…” Error
When Telegram gets stuck on “Connecting…”:
- Close other apps consuming bandwidth.
- Disable VPN or Proxy under Settings → Data and Storage → Proxy Settings.
- On Desktop, press Ctrl + R to force reload server connection.
- Test your internet on a browser to ensure it’s not a local ISP issue.
If you’re in a region with restrictions, set MTProxy server from Telegram’s official proxy list.
9. Update Notification Not Appearing After New Version
Telegram sometimes takes a few hours to push major updates via regional stores.
Workarounds:
- Use Telegram Desktop’s built‑in auto update option under “Advanced Settings.”
- Visit telegram.org/apps for direct APK download (Android only).
- Join @TelegramNews channel to get official update alerts first.
