This live is gated behind a TikTok bot-check, so the server can't fetch the stream. Open the live page in your browser, solve the CAPTCHA, then come back and press Check / Start.
Leave the time window empty to watch 24/7. Set From 22:00 / To 06:00 to only record overnight. Times are Bangkok time. The server checks every ~45s and auto-starts recording when an account goes live (one recording at a time).
