WhatsApp Not Working? 10 Fixes That Actually Work (2026)

Overview: If WhatsApp is not working, first check whether it is down for everyone or just you. If it is a global outage, no fix on your phone will help, so you wait. If it is just you, the cause is almost always your connection, an outdated app, a full phone, or a setting that blocks WhatsApp in the background. This guide shows how to check if WhatsApp is down, then walks through 10 fixes in order from fastest to most thorough, plus targeted fixes for WhatsApp not connecting, not opening, calls, notifications, and WhatsApp Web.

For businesses, WhatsApp going quiet means customers waiting. If you run customer messaging from a browser, a WhatsApp bulk message sender free tool keeps working from any computer even when your phone is the problem.

Before changing any settings, spend 30 seconds checking for an outage:

• Open an outage tracker such as Downdetector and look for a spike in WhatsApp reports.
• Search "WhatsApp down" on X or Google News for recent posts.
• Ask someone on a different network whether WhatsApp works for them.
• For the WhatsApp Business Platform, check Meta's status page.

If WhatsApp is working for everyone else, the problem is on your device. Work through the fixes below in order.

Fix 1: Check Your Internet Connection

Most WhatsApp problems are connection problems.

• Open a website in your browser to confirm the internet works.
• Switch between Wi-Fi and mobile data.
• Turn Airplane Mode on for 10 seconds, then off.

Result: your phone gets a fresh connection to the network.

Fix 2: Restart Your Phone

A restart clears temporary glitches in the app and the phone's network settings.

• Power the phone off completely, wait 30 seconds, and turn it back on.

Result: background services that WhatsApp depends on restart cleanly.

Fix 3: Update WhatsApp

Old versions stop working properly and miss bug fixes.

• Android: open the Play Store, search WhatsApp, and tap Update.
• iPhone: open the App Store, tap your profile, and update WhatsApp.

Result: you are on the latest version with current fixes.

Fix 4: Clear Cache (Android) or Offload the App (iPhone)

Corrupted temporary files can stop WhatsApp loading.

• Android: Settings > Apps > WhatsApp > Storage > Clear cache. Do not tap Clear data.
• iPhone: Settings > General > iPhone Storage > WhatsApp > Offload App, then reinstall from the same screen. Your chats stay on the phone.

Result: WhatsApp rebuilds its temporary files without deleting chats.

Fix 5: Allow Background Data and Turn Off Data Saver

If WhatsApp is blocked in the background, messages only arrive when you open the app.

• Android: Settings > Apps > WhatsApp > Mobile data, and turn on Background data. Turn off Data Saver.
• iPhone: Settings > WhatsApp, and turn on Mobile Data and Background App Refresh. Turn off Low Data Mode.

Result: WhatsApp can connect even when it is not on screen.

Fix 6: Set the Date and Time to Automatic

A wrong date or time stops WhatsApp connecting securely, often with a "date is inaccurate" message.

• Android: Settings > System > Date & time > turn on automatic date and time.
• iPhone: Settings > General > Date & Time > turn on Set Automatically.

Result: your phone clock matches WhatsApp servers.

Fix 7: Free Up Storage Space

WhatsApp needs free space to download messages and media.

• Delete large videos, unused apps, and old downloads. Aim for at least 1 GB free.
• In WhatsApp, use Settings > Storage and data > Manage storage to remove large files.

Result: WhatsApp has room to save new messages.

Fix 8: Turn Off VPN, Proxy, or Ad Blockers

VPNs, proxies, and some DNS or ad-blocking apps can block WhatsApp servers.

• Disconnect any VPN and test WhatsApp again.
• Remove any proxy set inside WhatsApp under Settings > Storage and data > Proxy.

Result: WhatsApp connects directly to its servers.

Fix 9: Check App Permissions and Battery Optimisation

Missing permissions break calls, media, and notifications.

• Allow Microphone, Camera, Notifications, and Contacts in your phone's WhatsApp settings.
• Android: Settings > Apps > WhatsApp > Battery > set to Unrestricted.

Result: your phone stops putting WhatsApp to sleep.

Fix 10: Back Up and Reinstall WhatsApp

The last resort for persistent problems.

• Back up first: Settings > Chats > Chat backup > Back up.
• Uninstall WhatsApp, reinstall it from the app store, verify your number, and restore the backup.

Result: a clean install, with your chats restored from backup.

If WhatsApp is stuck on "Connecting..." at the top of the chat list, the app cannot reach its servers. Work through Fixes 1, 5, 6, and 8 in that order: connection, background data, date and time, then VPN. If it only fails on Wi-Fi, the router or network may be blocking WhatsApp. Try mobile data to confirm, then restart the router.

If WhatsApp will not open, closes immediately, or freezes, the cause is usually an outdated app, corrupted cache, or a full phone. Use Fixes 3, 4, and 7. If your phone's operating system is very old, check that it is still supported, since WhatsApp drops support for older Android and iOS versions over time.

A clock icon means the message has not left your phone, so it is your connection. One grey tick means it left your phone but has not reached the other person, usually because they are offline.

Each tick status and its causes are explained in this guide to WhatsApp messages not being delivered.

• Check microphone and camera permissions for WhatsApp.
• Switch to a stronger network. Calls need a more stable connection than messages.
• Turn off VPNs and Low Data Mode.
• Turn off "Use less data for calls" if call quality is very poor.
• Make sure the other person has updated WhatsApp too.

Some networks and countries restrict internet calling. If calls fail only on one network, test on another.

• Check that notifications are allowed for WhatsApp in your phone settings.
• Turn off Do Not Disturb or Focus modes, or add WhatsApp as an exception.
• Android: set WhatsApp battery usage to Unrestricted so it is not put to sleep.
• Check whether the chat is muted or archived inside WhatsApp.
• If you use WhatsApp Web, notifications may appear on your computer instead of your phone.

• Refresh the page, or try another browser such as Chrome, Edge, or Safari.
• Clear the browser cache and cookies for web.whatsapp.com.
• Disable browser extensions, especially ad blockers.
• Make sure your phone has had internet recently, since linked devices need it at least every 14 days.
• Log out and scan the QR code again.

If the QR code will not scan or keeps expiring, this guide on fixing the WhatsApp Web QR code covers each cause step by step.

If WhatsApp shows "This account is not allowed to use WhatsApp" or a similar message, nothing is broken. Your number has been restricted or banned, often because of spam reports or an unofficial modified app.

The reasons, appeal steps, and how to avoid it in future are covered in this guide on WhatsApp Business account bans.

For a personal user, WhatsApp not working is an annoyance. For a business, it means unanswered enquiries, missed orders, and customers who go to a competitor. Plan for it before it happens.

• Link more than one device. Keep the business number linked on WhatsApp Web or desktop so the team can reply from a computer if the phone is lost, broken, or out of battery.

• Use a dedicated phone. Keep the business number off personal phones so one person's phone trouble does not cut off every customer.

• Back up daily. Set business chat backups to daily so a reinstall never costs customer history.

• Tell customers when you are back. After an outage, follow up with customers who messaged during the downtime.

Roklo runs from your browser through a linked WhatsApp session, so your team can keep sending personalised messages and follow-ups from any computer, without depending on one phone. No WhatsApp Business API is required.

If none of the fixes work, contact WhatsApp from inside the app: Settings > Help > Contact us (or Help center). Describe the problem, your phone model, and your WhatsApp version. If you cannot open the app, use the contact form on the WhatsApp website.

When WhatsApp is not working, start with one question: is it down for everyone or just you? If it is an outage, wait. If it is just you, work through the fixes in order: connection, restart, update, cache, background data, date and time, storage, VPN, permissions, and finally a clean reinstall with a backup.

Most problems are solved in the first five fixes. For businesses, the bigger lesson is resilience: link a second device, keep the number on a dedicated phone, and back up every day.

When you need to reach customers after downtime, Roklo works as a free bulk message sender from your browser.
