We just upgraded Splunk DB Connect from 3.9.0 to 3.11.0 on our Splunk Enterprise 9.0.3 Heavy Forwarder and getting warning "DBX cannot connect to task server"
Port 9998 is free , nobody is listening on it . We have updated Java 8 to Java 11 just now.
Rolling DB Connect back to 3.0.9 fixes the issue, DB Connect starts working again.
Will appreciate any advice.
Thank you!
