HP Device Manager - Impossible to capture image

Hi there,

I am currently setting up a new HP Device Manager environment for a PoC.
I have set up everything, and everything works. 

Sending tasks to the clients works fine.

I have configured 1 thinclient as example for capturing images etc.

But whatever I do, it does not woirk.
I used the cached and the non-cached version, but I just won't work.

Error:

2018-03-09 11:18:18 [Error Details]: Capture image to the Master Repository. Failed to upload fil_019_t530 to /Repository/Images/fil_019_t530_1. Failed to execute CaptureImage task. ErrorCode: 1074176, Error Info: ../../Task/common/MachiningTask.h@39: Check image supported method error. ../../Task/linux/ImageTask_ThinPro6.cpp@127: For now ThinPro6 task image does not support SMB.

thx for the help in advance!
