Error message

can not found title

What it means

The kuaishou extractor mints a fresh cookie (createCookie), fetches the page, then reads the video name from <title>([^<]+)</title>. This error means the served HTML carried no title content — almost always an anti-bot or waf interstitial rather than the real video page. The request itself succeeded.

Solutions

1. Retry — the cookie is regenerated each run and a second attempt often passes.
2. Open the URL in an incognito browser to confirm the video is public.
3. Run from a different IP or network.
4. If the page renders but the title moved, update the regex.

Retry the full Extract 2-3 times with a few seconds of backoff — each attempt mints a fresh kuaishou cookie and transient risk-control failures often clear. Stop retrying once the failure repeats to avoid provoking the waf.

When it happens

Trigger: Kuaishou risk control serving a challenge the freshly minted cookie did not pass; deleted or region-locked videos; a page-shell change that drops the title tag.

Common situations: Datacenter IPs; bursts of requests from one IP; videos under moderation review.
