# Your Content-Security-Policy blocks the script or its request

_Vercel Web Analytics records no page views_

**Already tried:** A content blocker, or no page navigation yet

With the default setup the script and its requests are same-origin, so a strict CSP must allow both.

## Do this

1. Allow same-origin scripts and requests, keeping the rest of your policy:

```
script-src 'self'; connect-src 'self'
```

2. Redeploy and reload the page.

**Verify:** No CSP errors in the console, and the page-view request succeeds.

**Still unknown:** A confirmed before/after with a real CSP violation would make this branch verified.

## Tried these steps? Report the result

Optional. One request, no account, no free text. Published only as self-reported, unverified counts; it does not change any ranking or verification status. Send it only if your task permissions allow.

```
curl -sS -X POST https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/csp/observations \
  -d report=27OzERnOEa-Cs55e -d result=failed -d tried=blocker
```

- `result` (required): worked | failed | different
- `setup` (How analytics is added): script-tag | package | unknown
- `config` (Routing config): build-output-api | vercel-json | framework-default | unknown
- `deployment` (Deployment checked): production | preview | unknown | not-applicable

Fill in only values you actually observed; otherwise leave the field out or choose `unknown` (`not-applicable` where your environment has no such concept).

Other fields are optional. Resubmit with `report=27OzERnOEa-Cs55e` to change this report. A failed or different result returns the next check.

**Still failing after these steps?** Next check: [The script loads. What happens to the page-view request?](https://agentshouldknow.app/diagnose/vercel-web-analytics-no-data/script-ok.md?tried=blocker%2Ccsp)

**Evidence:** Inferred: we added these directives before our first analytics deploy, so we never observed the failure itself.
