I have here 3 different ESP32 WROOM boards like a NodeMCU32S
I could connect to the Enterprise WIFI a month ago. But now all of them fail to connect.
Im using PlatformIO in my project, but also the simple WPA-Enterprise Example compiled and uploaded with Arduino IDE fails to connect now.

I don't have the network config in my hands, I don't know what could have changed there.

Description:

I can't connect to the enterprise WPA2 network with MS-CHAPv2 Authentication.
I don't use a certificate, it was working like this for about 2 weeks and stopped working. No other device has issues with this WIFI.

Hardware:

Board: nodemcu-32s
Core Installation version: 1.12.0
IDE name: Arduino IDE & Platform.io
Flash Frequency: 80MHz
PSRAM enabled: no
Upload Speed: 115200
Computer OS: Windows 10

Sketch:

//Change the code below by your sketch
#include <Arduino.h>

void setup() {
  Serial.begin(115200);
  enableLoopWDT();

  Config config("/config.json");
  String ssid = "sasdas";
  String username = "ASAS";
  String password = "SASAAS";

 esp_log_level_set("wifi", ESP_LOG_VERBOSE);      // enable WARN logs from WiFi stack
  WiFi.persistent(false);
  WiFi.setAutoConnect(false);
  // WiFi.disconnect(false, true);
  WiFi.mode(WIFI_STA);
 Serial.println( WiFi.scanNetworks());

  esp_wifi_sta_wpa2_ent_set_identity((uint8_t *)username.c_str(), strlen(username.c_str()));
  esp_wifi_sta_wpa2_ent_set_username((uint8_t *)username.c_str(), strlen(username.c_str()));
  esp_wifi_sta_wpa2_ent_set_password((uint8_t *)password.c_str(), strlen(password.c_str()));

  esp_wpa2_config_t wpae_config = WPA2_CONFIG_INIT_DEFAULT();
  esp_wifi_sta_wpa2_ent_enable(&wpae_config);

  WiFi.begin(ssid.c_str());
  uint8_t wifi_try = 0;

  while (WiFi.status() != WL_CONNECTED)
  {
    disableLoopWDT();
    enableLoopWDT();
    yield();
    delay(500);
    Serial.print(".");
    if (wifi_try > 100)
    {
      Serial.print("sleep");
      hard_restart();
    }
    wifi_try++;
  }
}

void loop() {
}
