Connect Droplet via SSH is Unstable. Encounter "timed out" occasionally.

Hi,

I created a docker droplet recently and try to create a generic docker-machine in my windows workspace.

However, I cannot successfully create the docker-machine. After debugging, I found out that I cannot successfully connect to my droplet with SSH every time.

Below is my command to create docker-machine:

 docker-machine -D --native-ssh create --driver generic --generic-ip-address=<IP> --generic-ssh-key <RSA KEY> remote

The command stuck when running SSH command, below is partial log:

About to run SSH command:
sudo hostname docker && echo "docker" | sudo tee /etc/hostname
SSH cmd err, output: <nil>:

I try to connect to my droplet with below command:

ssh root@167.71.214.248 echo hi

The command cannot always run successfully. Below is my screenshot:

I’m wondering what’s going wrong? Please kindly help me. Thanks a lot.
