I try to loadurl https://www.google.com and always get an error electron: Failed to load URL: https://www.google.com/ with error: ERR_PROXY_CONNECTION_FAILED . This problem has been bothering me for a week and I hope I can get your help

    newWin = new BrowserWindow({
        width: 400,
        height: 600,
        frame: true,
        maximizable: true,
        webPreferences: {
            devTools: true,
            webviewTag: true,
            nodeIntegration: true,
            enableRemoteModule: true,
            contextIsolation: false,
            preload: link
        },
    });
    
    newWin.index = arg.index;
    newWin.type = arg.type;
    
    //I have set ip and port here
    newWin.webContents.session.setProxy({
        proxyRules: "http://129.226.148.192:3128",
    }).then(() => {
        newWin.loadURL(`${arg.href}`);
    }).catch((err) => console.error(err));
    
    // I have configured the proxy account and password when I am here (login)
    newWin.on('login', (event, webContents, details, authInfo, callback) => {
        event.preventDefault();
        if (authInfo.isProxy) {
            callback('sub_1kni3wjb4g9i6pkhmbsz5qzd', 'stat900')
        }
    });

If anyone knows how to answer it would be greatly appreciated.
