we setup kibana dashboard in linux with port 5601 . Suddently setup dsahboard is not working. WE couldn't find the solution . So we change the port no 5601 to 5602 in kibana yml file. After restarting the server, i am able to lanuch the dashboard. But we need to run 5601 port since kibana dashboard is mapped to 5601. Any idea how can solve the issue.

It seems that another task is running on Port 5601. Check the running program on this specific port, kill it, and run the Kibana again.
