One drive backend issues

Hi,

I'm using duplicity with one drive backend to backup my pc.
My OS is raspbian on raspberry pi 2.
Duplicity version 0.7.10.

Error from log file using verbosity 9:
AsyncScheduler: running task synchronously (asynchronicity disabled)
Writing duplicity-full.20161028T162602Z.vol1.difftar.gpg
Checked quota in 1.345569s
Backtrace of previous error: Traceback (innermost last):

    raise ConnectionError(err, request=request)
 ConnectionError: ('Connection aborted.', error("(104, 'Connection reset by peer')",))

Looks like an issue with oauth authentication with one drive?
I already created the authentication key using the website provided by the duplicity execution.

Any additional info missing?

Please advise.

Thanks,
Lioz.
