Why can't I upload my book to the Blurb website?
Every time I try to upload my book it fails after about 60% of it has uploaded.
Which version of Lightroom are you using?
Try disabling your Computer Firewall,Antivirus
This happens if Lightroom is unable to reach Blurb servers when something is preventing it to connect.
Please refer Issues when uploading book to Blurb from Lightroom 5
Let us know if that helps.
