(Slim + Retrofit Android Studio App)Requests not working

I’m developing an android app using Slim and Retrofit to connect de API to the app, but I have a problem, when I’m working in my pc and I try the app using the Android Studio emulator everything works fine, but when I use my laptop with the same API and the same Android Studio project, it seems that the requests aren’t workin, I mean, when I press a button to login the app doesn’t do the request or the request doesn’t work and I dont know why.

Anyone could know how to fix it?

Thanks a lot
