unsuccessfully backups

Like others this product doesn’t backup anymore. It either get stuck in the middle “The backup attempt has finished, apparently unsuccessfully (Dec 17 08:10:55)” or partially backing up: (Not finished).
It also doesn’t uploads to Google Drive anymore.
This is a new website.
This is the log from the ‘not finished’ backup.
