WhatsApp keeps a constant, encrypted connection between your phone and Meta’s servers so that messages and calls arrive in real time. When that connection breaks, the app shows a banner at the top and messages wait with a clock icon. The check on this page requests whatsapp.com from an outside server, so you can tell whether WhatsApp is answering at all before you blame your phone.
Messages, calls and media fail in different places
Text messages are small and get through on almost any connection. Photos, videos and voice notes are uploaded and downloaded separately and need more bandwidth, so they are the first to stall on weak signal. Voice and video calls need a steady, low-delay link and suffer most from crowded Wi-Fi. Status updates and channels travel through yet other parts of the service.
That split means a partial problem is common. If texts send but photos hang, the cause is usually bandwidth or storage on the phone, not a WhatsApp outage.
Signs and what they point to
| What you see | Likely cause | What to try |
|---|---|---|
| Clock icon on sent messages | Phone not connected to WhatsApp | Toggle airplane mode, check data access |
| Connecting banner at the top | Link to servers lost | Allow background data, disable battery saver |
| One grey tick for a long time | Recipient offline or unreachable | Try another contact to compare |
| Media download fails | Weak connection or full storage | Free storage, switch to Wi-Fi |
| WhatsApp Web shows phone not connected | Phone offline or link expired | Wake the phone, relink in Linked devices |
Getting WhatsApp to connect again
- Look at the check first
A slow or failed result means WhatsApp’s side is struggling and the best move is to wait a few minutes.
- Toggle airplane mode
This forces the phone to build a fresh connection and clears most Connecting banners.
- Allow background activity
On Android, set WhatsApp’s battery use to Unrestricted. On iPhone, turn on Background App Refresh for WhatsApp.
- Check storage
A nearly full phone stops media from downloading. Settings, Storage and data in WhatsApp shows what takes space.
- Update WhatsApp
Very old versions stop working entirely after WhatsApp retires them.
- Restart the phone
It resets the network stack and is quicker than any reinstall.
Linked devices and WhatsApp Web
WhatsApp Web, the desktop apps and tablets work as linked devices. They keep their own connection to WhatsApp, so they can go on working for a while when the phone is offline, but they still need the phone to sign in from time to time. A linked device that shows old messages only, or asks you to scan a code again, has usually lost its session rather than run into an outage. Remove it under Linked devices on the phone and link it again.
Verification codes and a new phone
Moving WhatsApp to a new phone is where many people decide the service has failed. Registration needs a six-digit code sent to your number by SMS or voice call, and if you request it several times in a row, WhatsApp makes you wait before it sends another, with the waiting time shown on screen. Requesting again does not shorten it. If the account has two-step verification, WhatsApp also asks for the PIN you set; without the PIN, the account can only be reset after a waiting period of seven days. Have both ready before you switch.
A phone with the wrong date produces another error that looks like an outage. WhatsApp checks the clock when it connects and refuses to work while the date is far off, telling you to correct it. Setting date and time to automatic fixes it at once.
Old phones and retired versions
WhatsApp drops support for older versions of Android and iOS on a regular schedule. A phone that misses the cut stops connecting, and no outage is involved. The WhatsApp help center lists the current minimum versions. If an old tablet or a spare phone stops working with WhatsApp while your main phone carries on, its operating system is the likely reason.
Channels and Communities
Channels, the one-way broadcast feeds in the Updates tab, and Communities, which group several chats under one admin, run alongside ordinary chats. A channel that stops updating, or a community announcement that does not arrive, can be a feature-level glitch while messages flow normally. If personal chats send and receive while a channel stays frozen, wait; your phone is fine. Before reinstalling over any of these problems, run through the steps for telling an outage from a phone problem.
Business accounts
Businesses that use the WhatsApp Business Platform depend on Meta’s developer services as well as the app. Meta Status reports incidents in those business tools, which is why it is listed among the help links here. Personal accounts are not covered in detail there.

Questions about WhatsApp
What do the ticks on WhatsApp messages mean?
A clock icon means the message has not left your phone yet. One grey tick means it reached WhatsApp's servers. Two grey ticks mean it reached the other phone, and two blue ticks mean it was read, unless the other person turned off read receipts.
Why does WhatsApp keep saying Connecting?
The banner appears when the app has lost its live link to WhatsApp's servers. Most often the phone's connection is weak or a battery saver stopped the app in the background. Toggle airplane mode, allow background data for WhatsApp, and check the status above.
Why are my messages stuck on one tick?
One tick means your message reached WhatsApp but not the other phone. The other person may be offline, have no signal, have blocked you, or have their phone switched off. If messages to several contacts on different networks stay on one tick, an outage becomes more likely.
Why won't WhatsApp Web link to my phone?
Linking needs the phone online and the QR code scanned from Settings, Linked devices on the phone. A dim screen, an old browser or a weak phone connection can make the code expire. Refresh the page for a new code and scan it again.
Do WhatsApp, Instagram and Facebook fail together?
Sometimes. They belong to Meta and share some infrastructure, so a large Meta incident can hit all three at once. Smaller incidents usually stay inside one app or one feature, such as media downloads or status updates.
Will I lose my chats if I reinstall WhatsApp?
Only if there is no backup. Before reinstalling, open Settings, Chats, Chat backup and make a fresh backup to Google Drive on Android or iCloud on iPhone. When you sign in again with the same number, WhatsApp offers to restore it.
