ros连接probot机械臂可以ping通但是launch后出现问题

淮.

使用的ubuntu18.04 ros是melodic版
笔记本没有网口用了一个usb网卡转接的
编译没有问题，rviz也可以正常启动
连接机械臂后运行roslaunch probot_bringup probot_anno_bringup.launch robot_ip:=192.168.2.123后报以下错误

[ERROR] [1698892328.358786533]: Failed to receive message length
[ERROR] [1698892328.358898293]: Failed to connect interface client

[ERROR] [1698892328.885646712]: Failed to call service probot_heartbeat

虚拟机ip已经配置了，ping机械臂也ping的通，求大佬解答
