Tcp 127.0.0.1:9411: connect: connection refused

Docker Hub
1

I have changed approach to use spring annotations based tracking using @WithSpan.

I am see traces are generated from application and pushed to opel collector. I have defined pipelines to receive opel logs and export it into splunk/Jaeger/Zipkin.
Collector is reading traces now and pipelines are executing. We are stuck at one last step to push traces to exporters, failing with TCP connection refused.

I am able to connect to exporters through Spring application and able to push traces.
Issue is , communication is not established through docker

Exception:

Exporting to ZIPKIN

“: dial tcp 127.0.0.1:9411: connect: connection refused”, “interval”: “37.311690176s”}

Exporting to Splunk Collector

Any quick pointer for connection refused error?
