Splunk Db Connect not working after installation (The Java Bridge server is *not running*)

Background:
We have installed Splunk Db Connect in various Splunk servers and it has worked out of the box. However, in this particular server after installation of Splunk Db Connect the Java Bridge server cannot start successfully. We have the same server version of the JDK 1.7.0_51 installed which has been used in other Splunk installations of Splunk Db Connect.

The Splunk web UI shows the following message after providing the path to the JDK:

Welcome to Splunk DB Connect - the generic SQL database connector for Splunk

The Java Bridge server is not running

When we look at the jbridge.log file we see the following error:

Any help would be greatly appreciated.

This is indicating that a plaintext connection is being made to splunkd when it's expecting an SSL connection. Have you set enableSplunkdSSL to false in $SPLUNK_HOME/etc/system/local/server.conf? Or changed the splunkd certificate or cipher suite?

Your answer was spot on.

We had enableSplunkdSSL set to false in $SPLUNK_HOME/etc/system/local/server.conf for this Splunk installation.

Thank you.
