I found your script and used it for my own project. So I would like to share the solution with the comunnity.

You have a multiple client.connect into your code.

the line:

if (client.connect(clientId.c_str())) {

has to change to something like:

(client.connect("arduinoClient", willTopic, willQoS, willRetain, willMessage)) {

and remove the other line's from the void setup

client.connect("David_ESP_3", willTopic, willQoS, willRetain, willMessage);
  client.publish("tele/esp/LWT/3", "Online");
