I was recently working on Splunk Enterprise security to have a forwarder installed on the Linux machine and display it on the server. While working on this, I noticed that indexer search option is in red status. So , I went ahead and enabled the suggestion the system was asking. After that th server asked for a restart and now, it won't come up online. Could any one help here please? below is the log when I run Splunk start Done [ OK ] Waiting for web server at https://127.0.0.1:8000 to be available..............
