The page isn’t redirecting properly

Every now and then, when I try to access Reddit, this annoying "The page isn’t redirecting properly" (https://ibb.co/C0WD4c1). I use a few custom filter lists on Ublock (Actually Legitimate URL Shortener Tool and Bypass Paywalls Clean filter), however, this warning specifically occurs on Reddit.

Does anyone know what could be causing this? The only change I made was switching the DNS Secure to "Default Protection" upon a recommendation from the Mullvad extension.
