mDNS not working

[marcolino7]

Hi, I am trying to configure and make it work mDNS responder in order to make configuration more simple. Looking at varius code around online I found this code

WiFi.hostname("bigclock");
  if (MDNS.begin("bigclock")) {             // Start the mDNS responder for esp8266.local
    MDNS.addService("http", "tcp",80);
    Serial.println("mDNS responder started");
  }

Serial message was on console so MDNS.begin executed succefully. I tried to add before or after WiFiManager.begin(configManager.data.projectName); but it does not work. Anyone get mDNS work?
