Hi all, I have installed latest version of Elastic search and Kibana on red hat 7.6, both services are running but I am unable to connect to kibana from browser which is giving Kibana server is not ready yet. I saw error and checked instances but no instance was found. Can someone help in fixing the issue **Service Status:** sudo systemctl status kibana.service ● kibana.service - Kibana Loaded: loaded (/etc/systemd/system/kibana.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2019-05-20 04:26:48 PDT; 4s ago Main PID: 18508 (node) Tasks: 11 CGroup: /system.slice/kibana.service └─18508 /usr/share/kibana/bin/../node/bin/node --no-warnings --max-http-header-size=65536 /usr/share/kibana/bin/../src/cli -c /etc/kibana/kibana.yml May 20 04:26:48 scdl-sduipa-001 systemd[1]: Started Kibana. **ERROR LOG:** cat kibana.stdout {"type":"log","@timestamp":"2019-05-20T05:57:13Z","tags":["fatal","root"],"pid":681,"message":"Error: Port 5601 is already in use.

@abhishek_Shetty according to logs, another process is already running into the port 5601. Try to find what is the process running on that port with ```auto lsof -i :5601 ``` Then kill it and restart the kibana service. It should work then ---

Hi Tiagocosta, I did checked the port and found one kibana process is running but frequently its PDI is changing and I am unable to kill the process. Is their any command or method we can fix this issue. root@scdl-sduipa-001:/var/log/kibana# cat kibana.stderr FATAL Error: Port 5601 is already in use.

i hope you are running kibana not as a service Try killing kibana PID with below command and restart it ps -ef | grep '.\*node/bin/node.\*src/cli' Output: root 6297 1 1 May18 ? 00:18:50 ../bin/../node/bin/node --no-warnings --max-http-header-size=65536 ../bin/../src/cli kill -9 6297 ---
