Describe the bug

I encountered a reproducible issue when running the official LiteLLM example as described at https://openai.github.io/openai-agents-python/models/litellm/ with any openai modle ( e.g, openai/gpt-4o) and a valid OpenAI API key

The example works correctly on both Ubuntu and macOS environments. However, when executed on a Windows machine, the application consistently fails with a connection error: litellm.exceptions.InternalServerError: litellm.InternalServerError: InternalServerError: OpenAIException - Connection error.

Debug information

• Agents SDK version: 0.0.17
• litellm version: 1.72.2
• Python version 3.12.7

Repro steps

1. Follow the example code provided at the documentation link above.
2. Run the script in a Windows environment.
3. Observe that the connection to the API fails immediately.

Expected behavior

The code should function identically across all major OS platforms, including Windows.
