Cannot communicate with task server, please check your settings

[ycho1]

hello,

I downloaded and installed Splunk Enterprise 7.3.8 64 bits and Splunk DB Connect on Windows 2012 R2 64 bits.

Splunk DB Connect Version: 3.5.1 Build: 4

I keep getting the error when I set up Splunk DB 

Cannot communicate with task server, please check your settings.

I installed 

C:\Program Files\Java\jre1.8.0_291

JAVA_HOME

C:\Program Files\Java\jdk1.8.0_291

Can anyone give me an advice?

Did you check your settings?

DB Connect has several log files, one or more of which may shed light on the problem.  Have a look at \Program Files\Splunk\var\log\splunk\splunk_app_db_connect_*.log.
