Boris, It's nice to hear from you. While I don't have an answer, I thought, this thread might be useful to you: https://support.blurb.com/entries/24620879-Problems-with-book-upload-from-Lightroom-5-3 (you may have seen it already...)
It looks like it is a common problem, and most likely for large(r) books. Moreover, some people (see the comments here: https://forums.adobe.com/message/5551459 ) seem to have problems uploading the book they had uploaded previously. The only consistent solution is "after trying several possibilities recommended by the Blurb support which did not work I was advised to create a pdf and to upload it to the Blurb dropbox. " Somebody else reported that keeping the computer "active" helps... (so that it doesn't go in any type of power-saving mode). That sounds like some voodoo, but I can see it being responsible in some cases. E.g. when the power-saving mode includes stopping the HDD or something, possibly creating some pause in the upload stream, if the software on Blurb website is sensitive to that, it can consider the the connection broken.

I am trying to upload it from LR (first 5.5, now 5.6) to Blurb. It renders the PDF, it then goes on to "upload the pages". At around 80% it produces an error message without giving my re ason as to why it failed to upload the book. Any help or hints will be greatly appreciated.
