Messenger usually stops working because of a Meta outage, a weak connection, an outdated app or a bloated app cache. Check whether Messenger is down first, then update the app, clear the cache and switch networks. If it still fails, match your symptom to the fix below: not sending, not loading, no notifications or calls.
How to fix Messenger not working: first checks, in order#
- Rule out your network. Open a browser and go to facebook.com. If that doesn't load, it's likely a network issue.
- Check for a Meta outage. Open Downdetector for Messenger. If thousands of people are reporting issues, there's a Meta outage.
- Test another contact. Send a message to a different contact. If other conversations work fine, the issue is specific to that thread or recipient.
- Refresh the connection. Toggle airplane mode off and on, or switch between Wi-Fi and mobile data.
- Update the app and clear the cache. Update Messenger from your app store, then clear the cache (Android) or offload and reinstall the app (iOS), as described under Issue 2.
If none of those apply, work through the 8 fixes below.
Issue 1: Messenger not sending messages#
Messages queue and show a rotating icon rather than a delivered tick.
Cause: Almost always a local network problem.
Fixes (in order):
- Toggle airplane mode off and on to force a network refresh.
- Switch from Wi-Fi to mobile data or vice versa.
- Restart Messenger completely (swipe it away from recent apps, reopen).
- Restart your phone.
If the queued message still doesn't send after these steps, delete the message and retype it. Sometimes a corrupted outgoing message prevents the whole queue from clearing.
Issue 2: Messenger not loading or very slow#
The inbox loads but conversations don't open, or it spins indefinitely.
Cause: App cache has grown too large, or the app version is outdated.
Fix on Android:
- Go to Settings > Apps > Messenger > Storage.
- Tap "Clear Cache" (not "Clear Data" - that would log you out).
- Reopen Messenger.
Fix on iOS:
- Go to Settings > General > iPhone Storage > Messenger.
- Tap "Offload App" (this preserves your data but clears the cache).
- Reinstall Messenger from the App Store.
Issue 3: Messenger notifications not working#
You're getting messages but no sound, banner, or badge count.
Fix on iOS:
- Settings > Notifications > Messenger.
- Ensure "Allow Notifications" is on.
- Ensure "Sounds" and "Badges" are enabled.
- Also check: within Messenger, tap your profile photo > Notifications > toggle sounds and alerts on.
Fix on Android:
- Settings > Apps > Messenger > Notifications.
- Confirm all notification channels are enabled.
- Check that Messenger is not in the battery optimisation exemptions blocking background activity.
Issue 4: Messages delivered but not received by the other person#
Your messages show as delivered (two ticks) but the other person claims they didn't get them.
Troubleshooting WhatsApp instead of Messenger? Ticks work differently there - see our WhatsApp message delivery guide for the platform-specific causes.
Most likely cause: Their notifications are off, or the message landed in their Message Requests folder.
Messenger routes messages from people you're not connected to on Facebook into a "Message Requests" folder. If you messaged a business page or a non-friend, your message went there - not their main inbox.
Tell the recipient to check:
- Open Messenger.
- Tap the People icon (bottom of the screen on mobile).
- Tap "Message Requests".
Issue 5: Messenger calls not connecting#
Calls ring but drop, or one side has no audio/video.
Causes and fixes:
- Firewall blocking: Messenger calls use specific ports. Corporate or school networks often block these. Switch to mobile data.
- Microphone/camera permission denied: Settings > Apps > Messenger > Permissions. Enable Camera and Microphone.
- VPN interference: Disable your VPN while on the call. Messenger calls don't work well through most VPNs.
- Slow connection: Messenger calls need at least 1Mbps upload and download. Test your speed at fast.com.
Issue 6: Messenger not working on a business Page inbox#
If you manage a Facebook Page and Messenger isn't showing messages from customers, or messages appear but can't be replied to, there are specific causes:
- Messenger disabled for the Page: Meta Business Suite > Settings > Messaging. Make sure "Allow people to contact your Page privately" is toggled on.
- Response time setting expired: Pages with "Very Responsive" badges that miss too many messages get that badge removed, and sometimes see reduced message delivery. Keep your response rate high; check Meta's current requirements for the badge in Meta Business Suite.
- Page restricted: If your Page violates Community Standards, messaging can be restricted. Check for any warning banners in Business Manager.
Managing a business Page inbox at scale through the standard Messenger interface is painful - no team routing, no tagging, no SLA tracking. Tools like Instant Reply connect directly to the Messenger Platform API and give you a proper shared inbox where your whole team can respond, AI can draft replies, and no conversation gets missed.
Issue 7: Messenger logged out or account deactivated#
If you deactivated your Facebook account, Messenger still works - but only if you log in specifically through the Messenger app. If you can't log in at all, it may be a temporary deactivation or an account restriction from Facebook's systems.
Fix:
- Go to facebook.com and try to log in. If your account is restricted, you'll see a prompt to confirm your identity.
- Follow Facebook's account recovery flow - usually involves confirming your phone number or email.
Issue 8: Old messages or contact not found in search#
You're searching for an old conversation and it's not showing up.
Possible causes:
- The other person deleted the conversation from their end (only deletes it from their side - your copy remains unless you also deleted it).
- The Messenger search index needs to refresh. Force-close and reopen the app, then search again.
- You deleted the conversation yourself. If so, it's gone - Messenger doesn't have a recovery folder.
- The account you messaged was deleted by Facebook.
If nothing works: escalate to Facebook support#
In the Messenger app: tap your profile photo > Help & Support > Report a Problem. Describe the issue in detail. Facebook's support response time is slow (days to weeks), but reporting helps them identify widespread bugs.
Managing Messenger at scale for business#
If Messenger is a customer channel for your business and these issues keep interrupting your team's response flow, the real solution is not to keep troubleshooting the native app. Move to a proper inbox.
The Facebook Messenger Platform API gives you a stable, reliable connection that doesn't depend on the consumer app's bugs and notification issues. Instant Reply connects to this API, routes messages to the right team member, lets AI draft contextual replies, and gives you delivery receipts at the message level. No missed conversations, no cache issues.
