I find that when I see these kinds of errors, unplugging the USB cord from the HC and then reconnecting it will usually solve it.
I only ever see these issues with files that need to be downloaded from Ring. Files that are local never seem to give me problems. I think it may be due to an unstable network connection.
Out of curiosity, are you using a wired network connection from your computer to the router, or is it wireless?
I have not reported the issue to Ring so far either.
