What is the issue or error you’re encountering
I’m experiencing a persistent 5 2 2 ‘Connection timed out’ error specifically for my www subdomain (example) while my root domain (example) is working perfectly. Both domains are routing through a Cloudflare Worker. (h t t p s w w w blah com fails, while blah com succeeds.
What steps have you taken to resolve the issue?
Root Domain (example com): Configured as a ‘Custom domain’ on my Worker. This works, and my Worker successfully proxies content from my Cloudflare Pages project. WWW Subdomain (www example com): Configured in DNS as a C N A M E record. It points directly to my Worker’s workers.dev subdomain (e.g., my-worker-name my-account workers dev). It is proxied (orange cloud). Despite this setup and multiple cache clears (browser and Cloudflare DNS toggle), www example dot com consistently returns a 5 2 2. When I run www example com/cdn-cgi/trace, I get output, which suggests the request is hitting Cloudflare’s edge, but then timing out when connecting to the Worker.
