Splunk Connector not working

[questsin]

on windies 10 Enterprise and Anypoint Studio 7.8.0 and Splunk 8.1.3 running locally.

When I test the splunk mule 4 configurations with the right base URL of "http://127.0.0.1:8000/" I get the bellow error while its worth noting that Splunk Http Logger works.

Hello. i have same error could you please share with me solutions if you have :)

Hello @swichbalde and @questsin ,

After a lot of research, I figured out.

1. Splunk uses 8000 port for web UI meaning just the interface. Your actual splunk service runs on port 8089.
2. Protocol should be https not http. Set your base url to https://localhost:8089. (refer to image 1)
3. Inside Splunk Global Configuration, Go into Security Section and set the protocol to HTTPS and in the TLS configuration check the Insecure option. (Refer to Image 2) f.png">

Hope this helps! 👍
