One Tablet with 4.4.2 and another with 5.0.2 Both are showing this Error.
Today i tried it with an Windows Agent and the Windows Agent says, that the Inventory has been saved but the Inventoried Computer-List is empty.

I will see where is the problem with the Windows Agent. Maybe wrong URL. Is there a way to edit the URL after installation?
ocslog.txt on my Android now:
