I have:
Duplicati Version: Duplicati - 2.0.1.35_experimental_2016-12-13
Operating System: Win 10 Pro
Backend:
Trying to use Google Drive as a destination results in a 400 error even with a proper OAuth generated with no issues. I am pretty sure the connection to Drive is the problem somehow. Note: I am using a google drive through a University institution. I have used this google drive with previous versions of Duplicati.
Actual result: 400 error.
Expected result: Good connection

I have figured out the problem. I was typing in a google drive path using \ instead of /. Once I started using the forward slash it worked fine.
Great, also got this problem. It would be very nice if there could be a warning for this in the GUI.
