Xamarine forms app fails to get data from my web api

Question

Ive created a web Api which fetches data from my Sql Server database

I ran this Api through a web browser and it fetches my data very well, I ran it in postman tool its Ok(http:http://172.26.44.65/api/studentservices)

Ive published it in IIS and created an application which run fine.

 

I have now created a Xamarine forms application, for accessing it via my mobile phone and did every thing required as per the tutorials i see here on the web, However when it reaches accessing the web api to fetch data, i get the following error:

System.Net.WebException: failed to connect to /172.26.44.65 (port 80) after 120000ms: connect failed: ENETUNREACH (Network is unreachable)

 

What causes this error?
