Splunk cant start
@Judeumeh - Do you mean you are seeing "[failed] splunkd is already running error" while running "splunk start" command?
* That basically means your Splunk is already running.
* Maybe you are just not able to access Splunk UI.
* Check firewall rules to see if Splunk web port (default 8000) is accessible outside the machine if you are not using the browser locally on the machine.
I hope this helps!!!
could you share more infos?
