OpenAI proxy endpoints intermittently disconnect for GPT-5.5 / GPT Image 2

## Description

GPT-5.5 and GPT Image 2 requests are intermittently failing through the Comfy API OpenAI proxy, while other services/models appear to work normally.

Affected endpoints observed:

- `POST https://api.comfy.org/proxy/openai/images/edits`
- `POST https://api.comfy.org/proxy/openai/v1/responses`

Error logs:

## Expected behavior

Requests to GPT-5.5 and GPT Image 2 should complete reliably through the proxy.

## Actual behavior

Requests intermittently disconnect and fail after retries.

## Notes

Other services/models are working normally, so this does not appear to be a general local network outage. The issue seems specific to the Comfy OpenAI proxy endpoints or the upstream services behind GPT-5.5 / GPT Image 2.
