Hi @abhishek_Shetty,

As you already wrote kibana fails to start because another instance is using the same port.
Can you check the open port using:

lsof -PiTCP -sTCP:LISTEN | grep 5601

or using sudo if the process was started with a different user then the current

not getting any output
root@scdl-sduipa-001:/var/log# sudo lsof -PiTCP -sTCP:LISTEN | grep 5601
root@scdl-sduipa-001:/var/log# lsof -PiTCP -sTCP:LISTEN | grep 5601
