| Symptom | Cause and fix |
| --- | --- |
| The scene is not showing | Its eye is off in the Scene Panel — visibility is the on-air state. |
| The page stream answers 409 | The page is not live. Turn on live sync. |
| Go-live is refused | A check failed; the message names which and lists the failures. |
| Control panel widgets are missing on /view | They are stripped deliberately — operator surfaces never composite to air. |
| Fonts look wrong on the output | The font resolves on your machine but was not uploaded to the page. |
| Motion stutters | The output tab is backgrounded or throttled, or the browser source frame rate is below the show's. |
| No audio | Plates are muted by default, and browsers block audible autoplay until a gesture. |
| An animation did not replay after a reload | In-flight motion is not resumed. Re-take the element. |
