Service status
Live status is shown on the service status page. No uptime history is published until it is measured.
Owner input needed: set the status page URL (Settings, TT API Site). Until then this page cannot show live status, and this website never shows made-up uptime numbers.
While you check
Look up an error in the error reference, see the changelog or contact support. TikTok-side blocks can cause failures that no status page shows.
