TikTok not working? Quick 5UF VPN setup guide 
If TikTok still shows a black screen, fails to load, or redirects to Douyin even after you connect to a VPN, the problem is usually not just the IP address. TikTok also checks your current phone and network environment.
We recommend using the latest 5UF VPN app.
Quick setup:
- Fully close TikTok first.
- Turn on Airplane Mode and wait a few seconds.
- While Airplane Mode is on, manually turn Wi-Fi back on.
- Open the 5UF VPN app and connect to an available server.
- After the VPN is connected, open TikTok.
- Once TikTok loads normally, you can usually turn off Airplane Mode and return to normal mode.
Recommendations:
- Try to avoid Hong Kong servers, as they may affect TikTok region detection.
- For the same TikTok account, try to keep using the same server to avoid cross-region recommendations.
- If one server does not work well, switch to another server in the same region instead of changing countries too often.
If it still does not work:
- Switch between Wi-Fi and mobile data, then try again.
- Change to another non-Hong Kong server.
- Fully close TikTok and reopen it.
For long-term stable TikTok use, keep using the latest 5UF VPN app and try to maintain a stable server and network environment.
