Problem about Socket exception

update:

Found the Solution: If you're running the server locally and using the Android emulator, then your server endpoint should be 10.0.2.2:8000 instead of localhost:8000 as AVD uses 10.0.2.2 as an alias to your host loopback interface (i.e) localhost

Answer 1

1 open cmd

2 run ipconfig at cmd

3 copy IPv4 Address from cmd

4 at 'http://localhost:1337/auth/local/register' replace 'localhost' with your IPv4 Address

5 run your app

Answer 2

Instead of localhost, put your machine IP address. Mobile doesnt understand localhost.
