Hi guys when I run config file with sudo -u logstash /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/task.conf

It gives me the following error

What's wrong here? :smiley:

Thanks for any help !

Another program, possibly another instance of logstash, is already bound to port 5044. You cannot have two programs bound to the same port.
