Why do I get TypeError failed to fetch on every page refresh

[Lucent]

Did you figure this out? I have the same issue, but only with Edge Chromium. First request to ads goes through, but further that are handled by a fetch event in a service worker return that error. Is it cross-origin related?

@Lucent This is what I run now. Never tried to get ads working via service worker as I couldn't really figure it out.

self.addEventListener('install', function () { return self.skipWaiting(); });
self.addEventListener('active', function () { return self.clients.claim(); });

Did you have uBlock Origin enabled at the time and your site whitelisted? If so, I identified a problem with the extension on Edge that may have been the cause, for future visitors: uBlockOrigin/uBlock-issues#1478

@Lucent The change in uBO causing the issue was caused by a relatively recent change, it did not exist back in December 2019.
