Kibana URL is not working in browser

Elastic Stack Kibana
1

I have kibana-5.0.1-1.x86_64 installed in Redhat server. The services are up and running and i could see lsof -i :5601 has process but it is not working in browser.
The configuration are copied below.

server.port: 5601
server.host: "0.0.0.0"
server.basePath: "/kibana"
server.name: "servername.domain.name"
elasticsearch.url: "http://servername.domain.name:9200"
elasticsearch.requestTimeout: 30000

Where server.domain.name is the server name where logstash, kibana and Elasticsearch is installed.
I have not changed anything and with the above configuration it was working before.
Is there any commandlline commands to verify Kibana is working in the server itself. I mean by logging in to the Kibana server.

I have reverse proxy and proxy enabled in the Apache and there are no proxy errors in the Apache logs.

Please suggest what kind of debugging I have to make to find the issue.

Are there any errors in the terminal when booting up kibana?

You can turn on verbose logging in kibana.yml and it might help shed some light on the issue.

When go to visit kibana through the browser do you get any console errors?

In the kibana.stderr there are no errors. In the kibana.stdout I see the below message when verbose mode is enabled. I did checked in the server using Curl and it is working. I am sure there are no proxy errors in my Apache since there are no 502 error. I see 304 ( no modification) and 408 errors.

Browser Error:

•Make sure the web address https://server.domain.name is correct.
•Look for the page with your search engine.
•Refresh the page in a few minutes.

Curl Output in the Kibana server:
curl -sI http://x.x.x.x:5601/
HTTP/1.1 200 OK
