404 Not Found

What is the issue you’re encountering

After going to Analytics & Logs > Web Analytics and enabling RUM, I see a JS snippet automatically injected into my site. Unfortunately this snippet attempts to make POST requests to /cdn-cgi/rum but this always returns 404 Not Found. My site is using Cloudflare proxied DNS records.

What steps have you taken to resolve the issue?

Added a robots.txt with:

User-agent: *
Disallow: /cdn-cgi/

Observed that the 404 page for the /cdn-cgi/ routes differ from the 404 page configured for my site, implying that this is an error on Cloudflare’s side.

What feature, service or problem is this related to?

Web Analytics

I changed nothing but observed that this endpoint suddenly stopped returning 404 over the weekend. :person_shrugging:
