Check your knife configuration and network settings**

Answer 1

Use these commands on vm local workstation, vm local node and local pc. This will help you to resolve:

sudo apt update
sudo apt install ssh
sudo ufw allow 22
sudo chmod -R 777 /etc

Answer 2

This means knife was not able to open an SSH connection to the target you specified. SSH into the target host manually and look if there's any connection/networking issue. If you get some additional errors post them here.
