Troubleshooting

403 Forbidden Error

Why verification gets blocked, and how to confirm your install anyway.

A 403 Forbidden response means your site refused the automated request from Sonar's verification check. Your visitors aren't affected. Only our checker is blocked.

Common causes

  • Cloudflare: Bot Fight Mode or a challenge page blocks automated requests.
  • Web application firewall (WAF): your host's security layer treats the check as a bot.
  • IP or country restrictions: the site only allows certain networks.
  • Password protection: staging sites and private stores reject anonymous requests.

Confirm your install manually

  1. Visit your website in a normal browser.
  2. View the page source (Ctrl+U, or ⌘⌥U on a Mac).
  3. Search for tracker.js. If you find it, the snippet is installed.
  4. Reload the Sonar dashboard. Your visit should appear within a minute or two.

Detecting real traffic is a more reliable signal than the automated check, because it proves the whole pipeline works end to end.
