Can't download 3.8.5

Tried to update firmware on my Pixhawk 2.1 with Arduplane 3.8.5 and got error from MP.


Tried to find it on firmware server here http://firmware.ardupilot.org/Plane/ but can’t find it. Something went wrong or I do something wrong?

I have the same issue on a Pixhawk with MP 1.3.57. Issue tracked on github: https://github.com/ArduPilot/MissionPlanner/issues/1915
