electron-updater not detecting any updates - electron

Question

i am making an app using electron
i already did everything regarding auto-updating the app
but its not detecting the new release (1.0.1) when opened, although i released it using electron-builder.
i did commit and checked everything
here is my code:
main.js:
function createWindow () {
// Create the browser mainWindow.
mainWindow = new BrowserWindow({
useContentSize: true,
show: false,
title: "My app",
webPreferences: {
preload: path.join(__dirname, './preload.js'),
plugins: true,
nodeIntegration: false,
webSecurity: false
}
})
registerKeys()
Menu.setApplicationMenu(createMenu());
mainWindow.loadFile(path.join(__dirname, 'index.html'));
mainWindow.once('ready-to-show', () => {
autoUpdater.checkForUpdatesAndNotify();
});
};
autoUpdater.on('update-available', (updateInfo) => {
dialog.showMessageBox({
type: "info",
buttons: ["Ok"],
title: "Update Available",
message: "There is a new version available (v" + updateInfo.version + "). It will be installed when the app closes."
});
}
);
ipcMain.on('restart_app', () => {
autoUpdater.quitAndInstall();
});
package.json:
