qt tcp 连接秒断连

问题：
tcp连接总是秒成功后断连

debug会出现下面这些

onecore\net\netprofiles\service\src\nsp\dll\namespaceserviceprovider.cpp(550)\nlansp_c.dll!00007FFDA2A1D93D: (caller: 00007FFDD8BEACF6) LogHr(1) tid(336c) 8007277C ´Ë·þÎñ²»´æÔÚ¡£ÔÚÖ¸¶¨µÄÃüÃû¿Õ¼äÖÐÕÒ²»Õâ¸ö·þÎñ¡£

我重装了qt，装的时候勾上MingG 32的编译器，用起来就没事了，tcp可以稳定连接，不过还是会报上面的warning

窗口源码：

#include "login.h"
#include "ui_login.h"Login::Login(QWidget *parent) :QWidget(parent),ui(new Ui::Login)
{ui->setupUi(this);sock = new QTcpSocket(this);//Login的成员变量QTcpSocket*sock->abort();//与服务器连接成功会发出信号connect(sock,&QTcpSocket::connected,[this](){chatwindow = new ChatWindow(sock,this);chatwindow->set_user_name(ui->usernameTextEdit->text());chatwindow->show();this->hide();QMessageBox::information(this,"连接提示","连接成功！");});connect(sock,&QTcpSocket::disconnected,[this](){QMessageBox::warning(this,"连接提示","异常！连接断开！");});
}Login::~Login()
{delete ui;
}//连接按钮
void Login::on_pushButton_clicked()
{QString name_string = ui->usernameTextEdit->text();if(name_string.count() ==0){QMessageBox::information(this,"输入提示","请输入用户名！");return;}QString ip_string = ui->ipTextEdit->text();QString port_string = ui->portTextEdit->text();qDebug() << ip_string;qDebug() << port_string;sock->abort();sock->connectToHost(QHostAddress(ip_string),port_string.toInt());
}

debug内容
在这里插入图片描述

//Chatwindow的源码

#include "chatwindow.h"
#include "ui_chatwindow.h"ChatWindow::ChatWindow(QTcpSocket* sock_ref,QWidget *parent) :QWidget(parent),ui(new Ui::ChatWindow)
{ui->setupUi(this);this->sock = sock_ref;//ChatWindow的成员变量QTcpSocket*qDebug()<< "ChatWindow start";
}ChatWindow::~ChatWindow()
{delete ui;qDebug()<< "ChatWindow end";
}void ChatWindow::set_user_name(QString user_name)
{msg["user_name"] = user_name;qDebug()<<"ChatWindow set user name :" << msg["user_name"];
}void ChatWindow::on_sendPushButton_clicked()
{}
