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  
`http://192.168.1.115:8100/?devapp=true`

But, from my Android device, on my office laptop it gives the following error  
`net::ERR:CONNECTION_TIMED_OUT( http://192.168.1.115:8100/?devapp=true)`

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