WhatsApp Messages Not Sending — 6 Fixes

Understanding WhatsApp Delivery Indicators

Clock = not sent. One grey tick = reached servers but not recipient. Two grey = delivered. Two blue = read.

Fix 1: Check Your Internet Connection

WhatsApp requires an active internet connection. Test by loading a webpage.

Fix 2: Force Close and Reopen WhatsApp

Android: Recent Apps → swipe away. iPhone: swipe up → flick WhatsApp up. Reopen — this clears a stuck message queue.

Fix 3: Check WhatsApp Server Status

Visit isitdownrightnow.com for WhatsApp. Global outages affect millions simultaneously.

Fix 4: Clear WhatsApp Cache (Android)

Settings → Apps → WhatsApp → Storage → Clear Cache. Fixes corrupt cache files without deleting chat history.

Fix 5: Check if You Are Blocked

If messages to one person always show one tick: check if their profile photo and last seen are visible. If not, you may be blocked.

Fix 6: Update or Reinstall WhatsApp

Install the latest version. If still failing: back up chats (Settings → Chats → Chat Backup) then reinstall.
