  • Do you have an SSH server installed on your Ubuntu machine? Is the SSH server started? Are you able to ping your Ubuntu machine from Windows?

    How did you test that VirtualBox networking is working as expected?

From what I see, I assume that when you configured networking for your Virtual Machine, you chose NAT. NAT allows your VM to connect to the Internet, but it doesn't allow your Host to connect to your Guest. If you want that functionality, choose Host-Only in VirtualBox.

  1. Shut down your Ubuntu VM.
  2. From Preferences in VirtualBox, create a new Host-Only network.
  3. From the VM Settings for your Ubuntu machine, change the network type from NAT to Host-Only.
  4. Ensure that the chosen network is the one you created earlier.
  5. Start your Ubuntu VM.
  6. Note the IP address now, and try logging in with PuTTY.

For more details, refer here.
