Answer 1

Sometimes this error is caused when you have Mosquitto installed alongside ActiveMQ. this is a port number conflict caused by Mosquitto MQTT service running on port 1883 whiles Activemq server MQTT feature tries to run on that port. What you have to do is to either edit the mqtt conntector port in the conf/activemq.xml or commenting that line out like this

Then start the service again
