@hwf1324 I'd prefer if you revert the previous change you made. I think this guard is intentional, like the previous guard that was modified.

@seanbudd How about changing the exception thrown to log.debugWarning? But this is obviously not logical when retrying the download. And it would also import logHandler.

And I don't understand the reason for doing so?
