cannot assign requested address

This error is not a bug.
After I start the otel container there is an error, I don't know if this error is from k8s or bare metal.
can someone give me some advice?

prometheus: 2.36.1

It looks like you have port 9090 exported for your prometheus-operatord ClusterIP and prometheus-k8s NodePort. Could this be your issue?

Sorry, this is my fault, this ticket can be closed.

@wajika what reason? I had the same problem

Sorry, I forgot how to solve it, I remember it was not a technical problem, it was a configuration error.

Any one has solution or reason for this issue!

Hi, has anyone the solution for this? I'm getting the same error but I can't get was is my mistake (And I don't know a lot about net)

[gautampawnesh]

I resolved the issue, by fixing the configuration. I made a mistake into OTEL config prometheus endpoint. Then I followed https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/examples/demo/otel-collector-config.yaml and worked.

I faced the same error while I was following this architecture, and found that I had mistakenly configured the receivers' endpoint in the 'exporters' field. 😅
