NO_PROXY env var doesn't work after upgrade collector #10456

What happened?

Description

After upgrading opentelemetry-collector-contrib from version 0.81.0 to 0.101.0, otlp/elastic exporter is failing because it tries to send traces through the proxy set on env vars, but no_proxy var is also set for elastic URL, so it shouldn't use proxy.

Steps to Reproduce

Upgrade to collector-contrib 0.101.0 and set the following env vars:
"no_proxy_"="<elastic_url>",
"http_proxy"="<proxy_url>",
"https_proxy"="<proxy_url>"

Expected Result

Send traces to elastic without the proxy, because it is set in the env var no_proxy

Actual Result

Traces are attempted to be sent through the proxy

Collector version

0.101.0

I have updated the issue to reference the OTLP exporter instead of the Contrib's Elasticsearch exporter.

I am not able to reproduce, but I'm not sure if my testing is correct. Here is the config I used and the steps I followed:

exporters:

  otlp:
    endpoint: https://200.100.1.1:4327

      enabled: false

There is no mention of either the proxy IP or the original destination IP, so I'm not sure, but I the fact that there's no mention of the proxy IP as in the previous run makes me assume that the collector is trying to reach the original destination IP 200.100.1.1 and getting "error": "rpc error: code = DeadlineExceeded desc = context deadline exceeded, which is expected.

Judging by the log Error while dialing: dial tcp 127.0.0.1:1235:, the collector is trying to reach the proxy, which is expected.

Run Otelcol v0.101.0 with NO_PROXY and observe collector logs:

Thanks for your reply. I don't know why in my case it tries to send traces through the proxy. Finally, I unset the proxy variables and it sends traces to elastic without errors.

@diecgia I'll close the issue if that's OK. Please reopen (or comment on it and mention me if you cannot reopen) if you can find a reliable reproduction scenario for this.
