已经在config里修改了url，然后本地版本也是可以运行的。运行国内大模型没有问题，不知道是不是什么网络问题。
log如下：

### Terminal Traceback & Material to Help Reproduce Bugs | 终端traceback（如有） + 帮助我们复现的测试材料样本（如有）

_No response_

Start with config.py and request_llms/bridge_chatgpt.py, especially the requests.post call and proxy handling shown in the traceback. Reproduce the failure with the reported third-party endpoint and verify the configured URL, proxy format, and hostname resolution. Done means the cause is identified and the GPT or Claude connection either works with valid settings or reports a specific actionable error.
