Android app failed to connect to local server over WIFI

Question

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.

Have a look at the firewall. Switch it off for a test. – greenapps Aug 15 '18 at 09:22 — greenapps, Aug 15 '18 at 09:22

Your problem solution is simple ->

You have to allow external devices to connect your server.
