# You moved the 404 route. What does the script URL return now?

_Vercel Web Analytics records no page views_

**Already tried:** A catch-all 404 route is swallowing the analytics path

Redeploy, then request the same script URL again:

```
curl -sS -i https://YOUR-SITE/PATH/script.js | head -c 800
```

Pick what you observed (each link is a plain GET):

- [Still your own 404 page](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/other-catch-all.md?tried=catch-all-404)
- [Now Vercel's own NOT_FOUND](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/not-enabled.md?tried=catch-all-404)
- [Now 200 with JavaScript, but still no data](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/script-ok.md?tried=catch-all-404)
- [Something else, or I can't tell](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/unresolved.md?tried=catch-all-404)

**Evidence:** Follow-up checks derived from the first branch.
