Splunk DB Connect: How to resolve "Unable to establish a secure connection to DBX Server" error after changing port 9998 to a different port?

[sakeebhossain]

I am trying to setup Splunk on a Linux machine, along the Splunk DB Connect add-on. However, when I open the add-on, I receive the following error:

"Can not communicate with task server, please check your settings."

Checking my log files, it seems that the port 9998 (the one set by default) is already in use. I tried changing the port to something else, as suggested by some answers to similar problems but then I receive an additional error:

"Unable to establish a secure connection to DBX Server, please make sure it is started and listening on 9998 port or consult documentation for details"

How can I resolve this?

So I've managed to resolve it! Turns out all I needed to do was to navigate to Configuration > Settings > General and ALSO change the task server port to the new one in the "JVM Options" and "Task Server Port" boxes.

Possible solution would be a missing JRE installation.

https://docs.splunk.com/Documentation/DBX/3.15.0/DeployDBX/Prerequisites#Java_Runtime_Environment_.2...

Validate JRE is installed:

java --version

If nothing is returned, then on Ubuntu:

sudo apt install default-jre

Restart Splunk.

changed to a different port other than port 9998, e.g. 9995 and works fine.

Hi adonio, I already tried this solution, (changing port to 1025 in dbx_task_server.yml) but I still get the second error I mentioned: "Unable to establish a secure connection to DBX Server, please make sure it is started and listening on 9998 port or consult documentation for details"
