I have tried to download backup of my site couple of times, but the link send to mail failed to download every time. The link just showed a blank white page. The error logs shows following errors:
Although I haven’t checked my error logs, I appear to be having the same issue. I just tried to download a backup from the link provided in the email and got a white page and no downloaded file.
As a workaround I downloaded them manually via SFTP after finding the backup files located in /var/discourse/shared/standalone/backups/default.

For fresh manual back up, the download link works fine. You have to download it immediately and if failed to download with in a couple of hours, then it wont work. Not sure weather its a security measure or a Bug!!
Yeah, as soon as the download is started the token expires (as a security measure). The error (white-page) you are seeing is a bug, instead a proper error message should be displayed. Fixed via:
