Why TeraBox Is Not Working
Understanding the cause helps you pick the right fix:
- Server downtime or maintenance
- Slow or unstable internet connection
- App bugs or an outdated version
- Cache or storage problems
- Account login issues
- Blocked permissions or restricted background data
TeraBox Not Working Fix (Step-by-Step)
1. Check your internet connection
A weak connection is the most common cause.
- Switch between Wi-Fi and mobile data
- Restart your router
- If you’re on office or public Wi-Fi, it may block TeraBox — try mobile data
2. Clear the app cache
A corrupted cache after an update causes errors and crashes.
- Go to Settings → Apps → TeraBox → Storage
- Tap Clear Cache
Important: clear cache first. Avoid “Clear Data” unless nothing else works — it signs you out and can remove unsynced files.
3. Update the app
An outdated version can break compatibility after an Android or iOS update. Update TeraBox to the latest version from the official Google Play Store (Android) or App Store (iPhone).
4. Fix login problems
If you can’t log in:
- Double-check your email and password
- Reset your password if needed
- Turn off any VPN or custom DNS app, then try again
- Clear browser cookies if using the web version
For a full walkthrough, see our TeraBox login failed fix guide.
5. Fix downloads not working
- Check you have enough free storage space
- Disable VPN if active
- Try a different browser for the web version
- Download during off-peak hours if speeds are slow
6. Fix upload failed errors
- Confirm your connection is stable — avoid switching networks mid-upload
- Reduce the file size if it’s very large
- Restart the app
- Make sure storage permissions are enabled
7. Fix the app crashing
- Restart your phone
- Update your Android or iOS version
- Clear cache (Step 2), then reinstall the official app if needed — note this signs you out

FAQ
Why does TeraBox say “network error” on good Wi-Fi?
Usually a VPN, DNS app, or network-level block. Turn the VPN off and try mobile data.
Will clearing cache delete my files?
No. Clearing cache is safe. Clearing data signs you out, so avoid it unless nothing else works.
Is the problem on my end or TeraBox’s?
If several fixes fail and others report the same issue, it’s likely a server outage — wait a few hours.
Final Thoughts
Most TeraBox problems — login errors, failed downloads, slow speed, or crashes — can be fixed with the steps above. Keep the official app updated and use a stable connection, and the app should run smoothly. If a problem persists after all these steps, it’s usually a temporary server issue that clears on its own.
