    Same issue exists on 2021.3.13f1, to which version should we upgrade to have stable version.

    We experience this issue on cdn (for addressables)

    I was having the same error using Unity 2020.3.24f1 for a UWP ARM64 Build for the HoloLens 2, against a CCD bucket.
    My initial solution was to move to a AWS S3 (publicly open) and replace the request's uri HTTPS to HTTP.

    I updated to 2020.3.28f1 and my CCD requests now work on the device.
