I'm getting this error while trying to restore elfinder using LibMan.
Here's are the 2 errors I'm getting as well as the stack trace:

Error LIB010 Failed to download resource from "https://cdnjs.cloudflare.com/ajax/libs/elfinder/2.1.41/sounds/rm.wav"

That target URL returns "403 Forbidden", so LibMan wouldn't be able to download it. The CDN might be configured to refuse download of .wav files.

We should have a clearer error message when something like this happens.

Has this been an issue on recent versions of LibMan (in VS2019 or with the latest CLI/build NuGet packages)? I saw this a few times in the past with CDNJS returning HTTP403 occasionally. It should be significantly mitigated by the retry loop added a few months ago when downloading resources, so I just wanted to check if we can close this.
