until 3 days ago I was using WiFiManager without problems. I install Arduino 1.8.9 and everything stop working with this message on serial monitor: xxxxxxxxxxxxxxxxxxx WM: Sent wifi save page WM: Connecting to new AP WM: Connecting as wifi client... WM: Connection result: WM: 4 WM: Failed to connect. So I reinstall arduino 1.8.7 and try again but the error is still there, dont know where and why. this are my headers:

include

include "ArduinoJson.h"

and I using this code: WiFiManagerParameter custom_WiFiRelay("WiFiRelay", "WiFiRelayName", WiFiRelay, 21); // Connect to WiFi network WiFiManager wifiManager; //set config wifiManager.setSaveConfigCallback(saveConfigCallback); //agregar nuevo parametro wifiManager.addParameter(&custom_WiFiRelay); //*RESET WIFIMANAGER***** //wifiManager.resetSettings(); //*** wifiManager.autoConnect("WiFiRelay");//coment serial.begin() if (!MDNS.begin("esp01")) {} server.begin(); strcpy(WiFiRelay, custom_WiFiRelay.getValue()); if (shouldSaveConfig) { Serial.println("saving config"); DynamicJsonBuffer jsonBuffer; JsonObject& json = jsonBuffer.createObject(); json["WiFiRelay"] = WiFiRelay; File configFile = SPIFFS.open("/config.json", "w"); if (!configFile) { Serial.println("failed to open config file for writing"); }

json.printTo(Serial);
json.printTo(configFile);
configFile.close();

}

I check the router, disable firewall PC, re-re-install arduino 1.8.9 and 1.8.7. Check code and compared to working examples. How can something that was working with arduino 1.8.7 until 4 days ago stop working installing arduino 1.8.9?
