Question posted in 
I’m developing an Android app that must connect to the server to retrieve some data. I’ve 2 devices connected on my local WIFI via a router: My development laptop (as server) and my development android phone (as client). The laptop has as IP address 192.168.41.50 and my Apache HTTP server is running on port 81.
My problem is the following:
If I run my android application to retrieve data into the server, it doesn’t work, it’s giving me a timeout exception:
D/OkHttp: <– HTTP FAILED: java.net.SocketTimeoutException: failed to connect to /192.168.43.50 (port 81) after 120000ms
But the same address is working on the laptop’s browser
How can I solve this problem.
