"The channel is retired" / "CoCoL.RetiredException" error w/Box [2.0.3.6]

I just tried setting up a backup to box.com and while the Test worked (created the folders on the destination) when running the actual backup I’m getting the errors below in the global log and no files are actually being written.

Any thoughts on what’s going on?

Note that this is current a TEST secondary backup so there’s no critical timeframe involved here.
