Cannot create new DB Connection in Splunk DB Connect

[rayleigh29]

Hi all,
I’m trying to add a new connection in Splunk DB Connect but I always get this error popup:

<?xml version="1.0" encoding="UTF-8"?>
<response>
<messages>
<msg type="ERROR">Not Found</msg>
</messages>
</response>

Symptoms:

• Can open the DBX UI normally
• When clicking "New Connection" — page attempts to load, then shows error above

Troubleshooting done so far:

• Confirmed Java installed and JAVA_HOME set
• Confirmed Task Server is running port 9998 is listening
• Reinstalled DB Connect and Java

Splunk Enterprise : 10.0.2

DB Connect : tried 3.18.6 and upgraded to 4.1.2 — same issue

Java Version : OpenJDK-17 (tried upgrading to OpenJDK-21 - same issue)

Thankyou for all the help!

Did DB Connect function previously? Please verify file permissions for the DB Connect app and ensure the user has adequate read/execute access.

splunk stop
chown -R splunk:splunk $SPLUNK_HOME/etc/apps/Splunk_DB_Connect
chmod -R 755 $SPLUNK_HOME/etc/apps/Splunk_DB_Connect

If your kvstore is corrupted, clean the kvstore

$SPLUNK_HOME/bin/splunk clean kvstore --app Splunk_DB_Connect

Then start splunk and test again.
