Client Not connect at real external Device

Nio74

Good Day,

Hi I am testing my client application externally with an android device but it does not connect to the server, if I test on the same machine in debug it connects perfectly, but if I install the app on the android device it does not connect, I have tried also to do the test with the server on a fixed PC and put the client on a laptop (believing it to be a god permission problem on the manifest) but it doesn't even work this way. I want to point out that on the server I opened the firewall on the incoming port and exit 6547.

Server:

QString Backend::startServer()
{
    if (!server->tcpServer->listen(QHostAddress::Any, 6547))
    {
        return "Error! The port is taken by some other service";
    }
    else
    {
        connect(server->tcpServer, &QTcpServer::newConnection, server, &ClientResearch::newConnection);
        //server->connectDb();
        return "Server started, port is openned";
    }
}

Client:

 client = new ClientResearch("192.168.1.8",6547);

void ClientResearch::connect2host()
{

bool conSock = tcpSocket->state()== QTcpSocket::ConnectedState;

if(! conSock )
{
timeoutTimer->start(3000);

tcpSocket->connectToHost(host, port);
connect(tcpSocket, &QTcpSocket::connected, this, &ClientResearch::connected);
connect(tcpSocket, &QTcpSocket::readyRead, this, &ClientResearch::readyRead);
}else {
    qDebug() << "socket already connect";

}


Where am I Wrong?

Hi,

Is your device connected to the same network as your computer ?
By firewall, do you mean the one installed on your computer ?

1 Yes my device connected to the same network, I have try at ping "192.168.1.8" but not work
2 Firewall of windows I have disabled but not ping
3 I'm trying to solve the problem but I haven't succeeded yet

Re: Client Not connect at real external Device

If you do not have any ping at all I do suspect your router firewall settings or port blocking on your router. code wise is looking ok as long as the server is at 192.168.1.8 ...

I solved,the problem was in the router,the wifi was isolated
