Solution:

You have got the wrong VCI setting so it will not connect with any cars.

Don’t set vcx se as SDConnect, set it as C6 VCI.

Run ConfigAssist on desktop, configure device as 1 XENTRY Diagnosis VCI, then close the ConfigAssist

Vxdiag Benz Configure Vci

Vxdiag Benz Configure Vci 2

After configuration, DAS will cumminicate with R171 without problem.
