I Followed the steps of 《SIMATIC_IOT2000_Setting_up_V2.1.1》.

But when I tried to connect via putty(3.2.1 Remote access with Putty SSH Connection),

I got an error and couldn't find the site.(PUTTY error. jpg )

I also tried ping the IOT, and the results were shown in IOT-2040PING.png;

172.20.10.12 What does this IP do?

The image I use is example-v2.2.0.wic

What should I do to communicate with iot-2040?
