title: How to configure mosquitto broker to increase the disconnection time to mqtt clients?
body: <p>The mqtt documentation explains that the maximum value of the keepalive is 18 hours 12 minutes and 15 seconds.</p>
  
  <p>But the mosquitto server disconnects the clients if it does not receive messages before 60 seconds plus a tolerance of 30 seconds that is to say maximum to 90 seconds. </p>
  
  <p>That is, I can not configure a keepalive more than 90 seconds.</p>
