Connecting my Vercel-hosted site to crawler tracking keeps failing. What's going on?

Updated June 30, 2026 · Reviewed by [email protected]

Vercel-hosted sites connect through Vercel's edge middleware rather than a plugin, so the most common failure is the middleware deployment itself: either it didn't deploy to all the regions your traffic hits, or a more specific middleware/route rule on your site is intercepting requests before Trakkr's code runs.

Double-check the integration was added to the correct Vercel project and environment (production, not just preview), and that no other middleware in your project short-circuits before it. If your site also sits behind Cloudflare in front of Vercel, the Cloudflare-vs-origin setup matters too: see the Cloudflare setup guide for how the two interact.
