I have configured splunk-connect-kubernetes on my cluster and I have told it to send data to splunk-light where I have configured HEC.

HEC is setup correctly because I can POST information directly. However, in splunk-connect-kubernetes I am seeing this in the logs:

2019-05-17 17:10:47 +0000 [error]: #0 Failed POST to http://splunk.default.svc.licence.local:8088/services/collector, response: {"text":"No data","code":5}
