backblaze connection issue?

[Steven Verbeek]

Hello,

I am using Duplicity 0.7.06 from the stable branch on Ubuntu 14.04 and I have tried two different servers on two completely different networks. No matter what I do I cannot upload to Backblaze B2 using Duplicity, the Backblaze python pusher and other tools by them all work fine. But duplicity fails when trying to upload.

Backblaze keeps sending me either

I contacted them about the errors and they said they were going to fix the 500 one, so that one can be ignored.

I run into similar issues while trying to use backblaze to backup about 200GB of data, this is why I rewrote the backblaze backend (and I'm using it with docker since then "speedy37/duplicity:alpine").
