1.The IPV4 network segment of your PC may not in 192.168.1.xxx.
The default network segment of xArm Controller is at 192.168.1.xxx (xxx is a number in 1-255), so your PC’s IPV4 network segment should be in 192.168.1.1-192.168.1.255 (the tail number should be from 1 to 255, and cannot be the same with the controller’s IP address).
If your PC’s IPV4 network segment is not at 192.168.1.xxx, please change it to 192.168.1.1-192.168.1.255.
