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

Start with CdnjsProvider.RefreshCacheAsync, then trace the request through WebRequestHandler.GetStreamAsync and CacheService.DownloadToFileAsync while reproducing restoration of elFinder 2.1.41. Check the failing rm.wav download and the resulting ResourceDownloadException; done means the reported restoration failure is resolved or produces a clear, actionable error.

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:
