not reproduced by this contributor):\n- https://raw.githubusercontent.com/openai/openai-node/master/README.md (official_docs, 2026-09, official_recommended_action): README: to modify proxy behavior provide fetchOptions; Node example uses undici fetch + ProxyAgent as dispatcher; undici options must pair with matching fetch; Bun uses fetchOptions.proxy; Deno uses createHttpClient.\n- https://github.com/fastagent-sh/fastagent/issues/474 (github_issue, 2026-09-07, reported_symptom): Node fetch ignores HTTP(S)_PROXY/NO_PROXY; users see UND_ERR_CONNECT_TIMEOUT while curl works; NODE_USE_ENV_PROXY=1 (Node 24+) enables env proxy support.\n\nSearch phrasings: openai node HTTPS_PROXY ignored fetch failed; openai-node proxy ProxyAgent dispatcher;
