# Troubleshooting: no data or nothing sent > Why the tag isn't recording, a tracking domain is stuck, or events aren't reaching an ad platform, and how to fix each case. Updated 2026-11-10 · Troubleshooting · https://kalmananalytics.com/support/troubleshooting-no-data/ Start with the symptom you're seeing. ## Verify installation never finishes You pressed **Verify installation** and it stays on **Waiting for the first page view…**. 1. **Is the snippet on the page?** Open a page of your site and view its source. Look for the snippet from **Integrations → Tracking**. If you use a site builder, check that the change was published. 2. **Is your domain allowed?** Check **Allowed origins** in **Privacy settings**. The tag refuses hits from any domain that isn't listed. A common miss is listing only `*.northwindhealth.com`, which covers `www.` but not `northwindhealth.com` itself. List both. In your browser's developer tools, a refused hit usually shows only as a CORS error. 3. **Is the workspace live?** The tag's hits are refused until the workspace has an active plan. That includes a preview workspace, one whose subscription has lapsed or failed payment, and a deleted one. Check **Billing**. 4. **Are you a bot to Kalman?** Hits from crawlers, headless browsers and page-preview tools are ignored. Test in a normal browser window. ## A Content Security Policy blocks the tag If **Verify installation** never finishes and your site sends a `Content-Security-Policy` header, open your browser's console on your site. A message like "Refused to load the script" or "Refused to connect" names the blocked host. Add your tracking subdomain to `script-src`, `connect-src` and `img-src`, and allow the inline snippet with a nonce or hash. See [Install the tag](/support/install-the-tag/) for the exact entries. ## Events are missing from the Event log - Open **Event log** with the last-10-minutes filter (the link under **Check it worked** on the install page), then do the step again. - An event name the browser isn't allowed to send (`provider_approved`, `refund_issued`, `refill_purchased` and the like) is refused. Those come from your platform. - A custom name must start with a letter and use only letters, numbers and underscores, up to 40 characters. A name that refers to a condition or medication is refused. - `identify` sends nothing if the email has no `@` or the phone has too few digits, and it only works on `https` pages. - A field in the wrong format (such as a SKU with spaces) is dropped, but the event itself still arrives. See [Track events](/support/tracking-events/) for the exact formats. ## The tracking domain is stuck - **Waiting for the CNAME record:** check the record's name and target on **Integrations → Tracking**. If your DNS is on Cloudflare, set the record to **DNS only** (grey cloud). Press **Check now** after a few minutes. - **We're activating your domain:** DNS is verified and HTTPS is being turned on. This usually takes a few minutes, and Kalman re-checks every 10 minutes. A workspace without a plan waits here until it has one. - **Activation failed:** remove the domain, check the record, and add it again. If it fails again, [contact support](/support/getting-help/). The tag keeps working from Kalman's own address in the meantime. See [Tracking domains](/support/tracking-domains/). ## Events arrive but don't reach an ad platform 1. Open **Event log** and switch to **Deliveries to Meta**. 2. Check the **Status** column: `sent`, `pending`, `skipped`, `failed` or `shadowed`. 3. For a skipped one, click **What we sent** to see the reason. The Meta page's **4. Preview** panel also shows "Not sent:" and a reason for your latest event of each type. | Reason | What it means | What to do | | ----------------------------------------- | --------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | `not_mapped` | The event isn't mapped to a Meta event. | Map it on the Meta page, if you want it sent. | | `outside_event_time_window` | Older than Meta's 7-day window. | Nothing. Newer events send normally. | | `workspace_...` | The workspace isn't live (preview, inactive, deleted, no BAA). | Choose a plan or check **Billing**. | | `consent_denied` | The visitor said no to ad sharing, or their browser sends Global Privacy Control. | Expected. Kalman respects it. | | `consent_missing` | Your consent mode is opt-in and the visitor hasn't said yes. | Expected under opt-in. See [Consent and GPC](/support/consent-and-gpc/). | | `clinical_unacknowledged` | A provider-decision event is mapped without the acknowledgement. | Review that mapping on the Meta page. | | `missing_required_website_field` | A website event without the visitor's user agent or the site URL, which Meta requires. Held, not sent. | Turn on **Send visitor user agent** and turn off **Leave the site URL out** on the Meta page, if your privacy review allows. | | `rejected_by_firewall` / `canary_blocked` | Kalman's privacy checks stopped the payload, for example a custom event name containing a sensitive term. | Rename the event. | | `test_code_missing` | The destination is in test mode without a test event code. | Add the code, or go live. | | `shadow_backlog` | Still waiting when the destination switched from shadow to live. It's never sent. | Nothing. New events send. | **Pending** deliveries are waiting, not lost: - **Waiting for the BAA:** nothing is sent until your account signs its Business Associate Agreement. See [Sign your BAA](/support/sign-your-baa/). - **Paused:** someone pressed **Pause sending** on the Meta page. Resume there. Anything still pending once Meta's 7-day window has passed is skipped. **Shadowed** means the destination is in shadow mode. Kalman records what it would have sent but doesn't send it. See [Shadow mode and going live](/support/shadow-mode-and-going-live/). ## Many events skipped for consent - If you use opt-in, every visitor who hasn't said yes is skipped. Check **Consent mode** under **4. Ad consent** on **Privacy review**. - Check that **Consent manager (CMP) the tag reads** matches the banner your site actually uses. - Some browsers and privacy extensions send Global Privacy Control, which counts as a no. ## Campaigns show as unknown Add the URL parameters to your Meta ads. See [Click IDs and intake links](/support/click-ids-and-intake-links/). ## What Kalman never sends Whatever the delivery status, Kalman never sends names, conditions, medications, intake answers or free text to an ad platform.
