I have installed VirtualBox and installed Ubuntu server version in VirtualBox VM. My host machine is Windows 10.
I have also installed Docker in my host Windows box. My intention is to use the docker CLI in Windows to connect to docker daemon (server) inside the VM.
I have made the changes in the Ubuntu VM and it is listening at port 2375.
tcp 0 0 127.0.0.1:2375 0.0.0.0:* LISTEN 2305/dockerd
Also I have set the environment variable DOCKER_HOST in my host(Windows) to the VM machine IP and port.
My Windows machine IP is 192.168.56.1 and the ping is working fine.

But when I try to connect from my Windows machine, it gives the following error:
error during connect: Get http://192.168.56.107:2375/v1.27/info: dial tcp 192.168.56.107:2375: connectex: No connection could be made because the target machine actively refused it.
Please find docker info output:

Can you please help me to resolve this?
