How to Fix It

Check your Wi-Fi or mobile data is turned on and working.

Try opening a website in your browser to confirm you have internet.
Switch between Wi-Fi and mobile data to see if one works.

If TikTok loads on mobile data but not Wi-Fi, the problem is your Wi-Fi.
Turn off any VPN app you have running.

VPNs can block TikTok or route traffic through a blocked region.
Restart your router by unplugging it for 30 seconds, then plugging it back in.

This refreshes your home network and often resolves DNS issues.
Clear TikTok's cache: go to Profile > Settings > Free Up Space, then tap Clear.

Corrupted cache files can cause network errors even when your internet is fine.

When to Call a Professional

This is a network or server issue. No professional is needed.

Frequently Asked Questions

Why does TikTok say 'network error' when my internet works?

Your internet may be working, but TikTok's servers could be down. Also, a VPN or DNS problem can block TikTok specifically while other sites load fine.

Does TikTok work on a VPN?

It depends on the VPN and which server you connect to. Some VPN servers are blocked by TikTok, or the VPN itself slows the connection too much to load videos.

Will clearing TikTok's cache delete my saved videos?

No. Clearing the cache only removes temporary app files. Your account, saved videos, and liked posts are stored on TikTok's servers — not affected by a cache clear.
