How to trace a port from my PC to a Lunix VM running on the same machine?

I created a Virtual Machine on my PC by installing Docker Toolbox.

My docker image seems to be running and should be forwarding https://localhost:44344 to my VM which is hosted on IP address 192.168.99.100:443 while forwarding http://localhost:32769 to 192.168.100:80.

However, when I try to browse the page, I get Unable to connect error in the browser.

How can I trace the connection between my localhost and my Docker-Machine to ensure the connection is reaching the endpoint? Or, are there other suggestions on how to troubleshoot this issue so I can view my website that is running on the VM using https://localhost:44344 or http://localhost:32769?
