_No response_

Start with .\crazy_functions\Internet_GPT.py, especially searxng_request and its requests.post call, then inspect how proxies and searxng_url are supplied. Reproduce the Windows Anaconda environment and compare the configured proxy with the reported 400 tunnel failure; done means the Internet GPT request no longer raises this ProxyError or the issue has a documented configuration diagnosis.
