After upgrading to MacOS Big Sur 11.0.1, I began having frequent connection issues, mostly “Your connection was interrupted” and occasional 404 and 503 errors) In most cases, the page loads after a few second, but sometimes I have to refresh the page. Sometimes, only a portion of the page loads at first. It almost seems CDN related.
Currently on Version 1.17.73 Chromium: 87.0.4280.67 (Official Build) (x86_64)
Using Mullvad VPN, uBlock Origin, Privacy Badger, Aggressive tracker/ad blocking, and strict fingerprint blocking. (Same settings as before upgrade without any issues). When I first installed Big Sur, I had Little snitch installed. I then update it to the Big Sur version, then uninstalled it on the assumption that it was causing the connect issues.
The connection issues do not occur in similarly-configured Firefox or Safari.
Has anyone else had similar connection issues after upgrade to Big Sur?
