Resilient Circuits not fully honoring HTTP_PROXY and HTTPS_PROYX env variables on new versions

[poleshe]

Description

Greetings!

In newer versions of Resilient, the variables do not seem to be respected. We can see them appear in these logs, right after packages log:

Connecting through proxy: 'http://redacted.for.privacy:443'

But the connection does not end up going through.

If using an older version, in this example 47.0.3691, we can see an extra log before STOMP Connection, and the connection goes through:

2025-01-27 15:31:16,919 INFO [stomp_component] Connect to Stomp...
2025-01-27 15:31:16,921 INFO [client] Connecting to redacted.for.privacy:65001 ...

2025-01-27 15:31:19,071 INFO [client] Connection established

We are not using any proxy parameter in the app config. What is the correct way to perform this connections? Are ENV Variables not supported anymore?

Thanks team!

Describe How to Reproduce

• Install latest version
• Set HTTP_PROXY and HTTPS_PROXY variables in the environment
• Connection does not follow proxy
