Hi, I started to get the error below after my Splunk was updated: HttpListener - Socket error from 127.0.0.1 while idling: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number I thought was some 'garbage' from previous version, but even after running a fresh install, the logs still show the same problem. I found this error while troubleshooting an issue with Splunk Kafka connector which is no longer sending messages to Splunk. I'm using this instance of Splunk for learning purposes. I upgraded from 6.5 to 7.0. Then a fresh installation was done using 7.2 with same issues. To provide a more complete picture: - Splunk was not initially set with SSL - I was troubleshooting why my Kafka connect was having errors sending data to Splunk - I noticed a few lines with the above message in the splunkd.log - I had a Splunk forwarder working before but it was disabled 2 months ago, so it's clear some components talk to themselves using SSL even with the option disabled - When I set Splunk to use SSL, instead of few messages on the log now I have hundreds of this message per minute - Thanks for the link provided. With the changes suggested now i'm getting non-stop the following message: HttpListener - Socket error from 127.0.0.1 while idling: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request My concern is to understand which components are trying to talk using SSL so I can better isolate the issue. The information on the logs so far are not enough for me to have a clearer picture. Saw a couple of discussions with similar error but couldn't find anything that could solve my problem. Thanks. ...
