TikTok serves over a billion monthly active users globally. When the app stops working — videos fail to load, the For You page is blank, or the app crashes on open — it is not always a platform outage. Most TikTok problems are fixable in under two minutes.
Quick check: is TikTok actually down?
Enter tiktok.com on WebsiteDown for a live server status check. TikTok does not maintain a formal public status page, so community reports are the best real-time signal. A sudden spike in user reports from multiple countries on WebsiteDown is a reliable indicator of a genuine outage.
TikTok videos not loading
Videos failing to load on TikTok is usually a network or cache issue, not a platform outage. TikTok delivers video content through a CDN (content delivery network), and regional CDN issues can cause video failures while the app itself appears functional.
Fixes to try: switch from WiFi to mobile data (or vice versa) to rule out a specific network issue, restart the app completely, and check if your internet connection can handle streaming (run a speed test at websitedown.com/speed-test — you need at least 5 Mbps for smooth video).
TikTok app crashing
If TikTok crashes immediately on launch, the most likely cause is an outdated app version or a corrupted app cache. Update TikTok to the latest version in your app store first. If it still crashes, clear the app cache: on Android, go to Settings → Apps → TikTok → Storage → Clear Cache. On iOS, you may need to uninstall and reinstall the app.
If TikTok crashes after a specific action (like opening a certain video or following a user), that is more likely a client-side bug introduced in a recent update — check if others are reporting the same behaviour.
TikTok upload not working
Upload failures on TikTok are common and usually caused by: video format incompatibility (TikTok works best with MP4 in H.264 format), file size limits (the app has a maximum upload size), or temporary upload server issues.
If your video format is correct and uploads still fail, wait 15 to 30 minutes and try again. TikTok's upload infrastructure occasionally experiences temporary degradation that resolves without any user action.
