Is my virtual machine or router to blame for being unable to access a VM website?

Looking to test my app over the network(or even public), but so far its only accessible by the computer I host the VM on.

make: VirtualBox, Vagrant, Homestead.

I have NAT, Bridged Adapter(192.168.1.17) and Host only adapter(192.168.10.10).

These are both available from my host computer, but they cant be accessed by my phone.

How can I debug this problem? My 3 best guesses- Bad VM config, bad router config, or Windows firewall blocks.
