No logs appear in Splunk Cloud Trail version. When I look at the logs of the splunk/fluentd-hec:1.2.0 container I see the error
" failed to flush the buffer. retry_time=2 next_retry_seconds=2021-12-03 08:25:21 +0000 chunk="5d239a1fb8d1cc285dc139c24de689c5" error_class=SocketError error="Failed to open TCP connection to https:443 (getaddrinfo: Name or service not known)"
@shthom Are you trying to stream these logs to splunk cloud using HEC token? please verify the firewall rules open from source to destination on port 443 and also validate the endpoint url is correct format.
