Splunk DB Connect is not working under the new release of Splunk.
The app is constantly loading and nothing happens.
DB Connect version is 3.2.0.
See the screenshot below.
The Java task server was not started because the Java installation was not appropriate, then the precheck was hanging a bit. After the JAVA reinstall it was working.
But I found out that the DB connect app use the older version of Python so in the future it will have more problems if the developer(s) not fixing it.
