How to Allow DevApp via Firewall

Hi All,
Was anybody successful in setting up IONIC DEVAPP on their office computer. I am able to connect to it via my personal computer but unable to connect it when hosted on the office laptop even on my home wifi network.

I can see my app on both office and personal laptop.

$ionic serve -c

I am able to access the Devapp hosted URL via my browser

But, from my Android device, on my office laptop it gives the following error

So, it seems more like a Firewall Issue rather than a network issue.
Kindly, help out if any one has faced this error.
