Title Body

I have 2 android devices, one acts as a server that is in tethering mode, and accepting connections to a port. The other device acts as a client that connects to the server hotspot and establishes a connection to the server via a port. (Everything is done without a router in the middle). The server code looks like this: (When the android server executes the code, the device is in tethering mode) ServerSocket server = new ServerSocket(PORT); while (true) { Socket client; client = server.accept(); ClientThread com = new ClientThread(client, this); Thread t = new Thread(com); t.start(); } The client code looks like this: (when the android client executes this code, the device is connected to access point) Socket client = new Socket(); int serverIP = wifiManager.getDhcpInfo().serverAddress; String stringIP = android.text.format.Formatter.formatIpAddress(serverIP); InetAddress address = InetAddress.getByName(stringIP); SocketAddress socketAddress = new InetSocketAddress(address, PORT); client.connect(socketAddress); I get the following error on the client java.net.ConnectException: failed to connect to /192.168.43.1 (port 12345): connect failed: ENETUNREACH (Network is unreachable) at libcore.io.IoBridge.connect(IoBridge.java:114) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:192) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:459) at java.net.Socket.connect(Socket.java:842) at java.net.Socket.connect(Socket.java:785) at com.alternatewifimeshmessaging.HostManager.clientConnect(HostManager.java:283) at com.alternatewifimeshmessaging.HostManager.client(HostManager.java:189) at com.alternatewifimeshmessaging.HostManager.run(HostManager.java:59) at java.lang.Thread.run(Thread.java:856) Caused by: libcore.io.ErrnoException: connect failed: ENETUNREACH (Network is unreachable) at libcore.io.Posix.connect(Native Method) a
