Here is the working solution to MB star diagnostic system SD Connect C4 Xentry online update Connection failed problem.

Problem goes like this:

I got the 06/2021 500G xentry hard drive for mb sd connect c4 doip. However, it failed to connect with network.

Reported an error “online update Connection failed. The connection attempt has failed.”

The error may be caused by wrong IP setting.

Subnet mask: 255.255.255.0

Then connect c4 via WiFi.

Follow this way:

172.29.127.1

255.255.255.0
