Why Is Duolingo Not Working? Here’s What You Can Do (2025 Fix Guide)

Whether you’re learning French during your commute or brushing up your Spanish before a trip, having Duolingo stop working mid-session is frustrating.

You tap the app, expect it to load… and nothing happens.

But don’t worry—this guide helps you fix it quickly, understand why it’s happening, and get back to learning.

Common Reasons Duolingo Isn’t Working (and What They Mean)

Here are the most frequent problems users experience:

  • App won’t open or freezes — due to outdated versions, app cache issues, or local device conflicts
  • Lessons not loading or stuck at 0% — often caused by poor internet connections or server-side errors
  • Progress not syncing between devices — syncing fails if your login session is corrupted
  • Notifications broken or delayed — happens when the app isn’t allowed to send background alerts
  • Audio or lessons missing — due to truncated downloads, data-saving limits, or permissions issues

Step-by-Step Fixes That Actually Work

These proven fixes resolve most “Duolingo not working” issues quickly and easily.

1. Restart the App & Device

🔁 Close the app completely (swipe away) and reopen it.
🔄 If needed, restart your phone or tablet.

This simple step clears temporary glitches and cache issues.

2. Check Your Internet Connection

Ensure you’re on a stable Wi‑Fi or reliable mobile data network.
Switch networks (Wi-Fi ↔ mobile) to test.
If that fixes it, your connection was the issue.

3. Update the App

Head to the App Store or Google Play Store and hit Update (if available).
Outdated apps often crash or fail.

4. Clear the Cache (Android Only)

Go to Settings → Apps → Duolingo → Storage.
Tap Clear Cache, then reopen the app.

🗑️ This removes temporary files causing errors.

For iPhone users, reinstall to clear issues.

5. Reinstall the App

  • Uninstall Duolingo
  • Restart your device
  • Reinstall from your app store
  • Log in again

This gives you a fresh, error-free installation.

6. Check for Server Outages

Sometimes the problem isn’t yours—Duolingo may be down for everyone.

  • Visit sites like Downdetector
  • Check @duolingo on X (Twitter)
  • If there’s a server issue, all you can do is wait—problems usually resolve within a few hours.

7. Ensure Sync Is Working

If progress isn’t syncing:

  • Log out and back in
  • Go to Settings → Sync Progress
  • Make sure your email or social login method is correct

Proper syncing ensures your learning progress stays safe.

8. Grant App Permissions

Missing sound or lessons? Make sure you’ve granted Duolingo access to:

  • Microphone (for speaking exercises)
  • Storage/data (for audio downloads)
  • Notifications (to get reminders and streak alerts)

9. Check Device Storage

Low storage can restrict new downloads.
Free up space by removing unused apps or media files, then reopen Duolingo.
