Same issue.
Updating Plugin BackUpWordPress (1/1)
Downloading update from https://downloads.www.ads-software.com/plugin/backupwordpress.3.6.0.zip…
An error occurred while updating BackUpWordPress: Download failed. Not Found
Funny think is, I can use wget to download the file directly from the URL https://downloads.www.ads-software.com/plugin/backupwordpress.3.6.0.zip
