Android 4.4 won't connect to Wifi after reboot?

Question

Java

Hello. Tell me please. For some reason, when programmatically connecting to Wifi in Android 6, everything works, and Android 4.4 also programmatically connects to Wifi, but after rebooting (Reboot), the device no longer connects, it goes (Authentication error).

WifiConfiguration conf = new WifiConfiguration();
                conf.SSID = "\"" + "some_ssid" + "\"";
                conf.preSharedKey = "\"" + "some_password" + "\"";

                int netID = wifiManager.addNetwork(conf);
                wifiManager.disconnect();
                wifiManager.enableNetwork(netID, true);
                wifiManager.reconnect();

Thank you.
