A Service-worker redirection 403 error is occurring on a self-hosted instance using Bunny CDN. matenauta shared the error message, which indicates that the script at https://CDN/javascripts/workbox/workbox-sw.js failed to load. Falco suspects a CDN misconfiguration. After inspecting matenauta’s instance at https://comunidad.btcarg.com.ar, Falco confirmed the misconfiguration, pointing out that every request becomes a redirect.
Hi, we are using Bunny CDN and see that error after last update (own hosted instance):
service-worker.js:1 Uncaught DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'https://CDN/javascripts/workbox/workbox-sw.js' failed to load.

This usually means that your CDN is misconfigured. Can you share your instance URL ?
Your CDN is definetly misconfigured. Every request becomes a redirect.
Example:
curl -I https://cdn-discourse.btcarg.com.ar/brotli_asset/google-universal-analytics-v3-706f1d28f0a97f67a47515c96189277240ec4940d968955042066d7873fd1fe8.js
