With an previously unused version of Calibre it would work if Kapersky was disabled. It would work the first time an earlier release was used but subsequent attempts at metadata download would fail with the same results. After a period of evaluation of potential probable causes I tried using earlier versions of Calibre. The remote host would reject the attempt to download the metadata and terminate the connection. This applied to metadata downloads from Amazon, Google and Good reads. I recently started having failures on Calibre Metadata download for books.
