Can’t able to access kibana dashboard - elasticsearch

Question

I am able to connect elasticsearch. However, I am unable to access kibana on 5601. Can anyone please help out this to work? Thanks in advance.
In the kibana.yml file, I have modified the server.host parameter to point to my domain.
Elasticsearch Version: 7.7.0
Kibana Version: kibana-7.7.0-1.x86_64
OS: Centos 7
JAVA Version: 11
kibana.yml
server.port: 5601
server.host: "my_domain"
elasticsearch.hosts: ["http://my_domain:9200"]

Kibana runs on port 5601 by default. This error message says that, when Kibana tried to start up & bind to port 5601, it couldn't because something else was already bound to port 5601.
Check if some application is already bound to port 5601. If yes, Try
another port.
If No, Then It would be easy to investigate the issue, if you could attach the contents of your /etc/hosts file.
