   Thanks for reporting this. The missing proxy support described here is now addressed by #382, merged on July 7, 2026.

   createLanguageModel(process.env) now honors HTTP_PROXY, HTTPS_PROXY, and ALL_PROXY (including lowercase variants), together with NO_PROXY. Requests are routed through an undici dispatcher supported by Node's native fetch.

   To use the fix, update TypeChat and install the optional proxy dependency:

   npm install typechat@latest undici

   Configure the appropriate standard proxy variable in your environment or .env file. For an HTTPS model endpoint, for example:

   HTTPS_PROXY=http://127.0.0.1:7890

   Replace that address with your actual proxy. If you call createOpenAILanguageModel or createAzureOpenAILanguageModel directly rather than using createLanguageModel, pass the proxy explicitly through the options argument as { proxyUrl }.

   See the proxy setup documentation.

   Closing as completed by #382. This addresses TypeChat ignoring proxy settings; it does not rule out separate VPN or proxy-connectivity problems, and we have not re-tested the original VPN setup. If the timeout persists with the updated version and a working proxy, please comment with the details so we can investigate further.
