FetchURL 未读取系统代理，在被墙环境下无法访问外网，而 Shell/curl 正常 || FetchURL has not read the system proxy and cannot access the external network in a blocked environment, but Shell/curl is normal #2455

What version of Kimi Code CLI is running?

kimi, version 1.43.0

Which open platform/subscription were you using?

managed:kimi-code（Kimi Code 账号登录）

Which model were you using?

K2.7 Code (kimi-for-coding)

What platform is your computer?

Linux 6.18.33.1-microsoft-standard-WSL2 x86_64 x86_64

What issue are you seeing?

在存在 GFW 的网络环境下，系统代理已正确配置，Shell 中的 curl 可以正常访问 YouTube/Google，但 FetchURL 工具会失败。

Shell 环境变量：

HTTP_PROXY=http://127.0.0.1:7890
HTTPS_PROXY=http://127.0.0.1:7890
http_proxy=http://127.0.0.1:7890
https_proxy=http://127.0.0.1:7890
curl 测试通过：

curl -I https://www.youtube.com # 200 OK
curl -I https://www.google.com # 200 OK
但 FetchURL 访问同样的 URL 会失败。

~/.kimi/logs/kimi.log 中的相关日志：

kimi_cli.tools.web.fetch:_fetch_with_service:158 - FetchURL service HTTP error: status=403, url=https://www.youtube.com
kimi_cli.tools.web.fetch:fetch_with_http_get:87 - FetchURL network error: Cannot connect to host www.youtube.com:443 ssl:default [Connection reset by peer], url=https://www.youtube.com
kimi_cli.tools.web.fetch:_fetch_with_service:158 - FetchURL service HTTP error: status=403, url=https://www.google.com
kimi_cli.tools.web.fetch:fetch_with_http_get:87 - FetchURL network error: Cannot connect to host www.google.com:443 ssl:default [Connection reset by peer], url=https://www.google.com
另外，执行 curl --noproxy "*" 会返回 Connection reset by peer，说明直连确实被墙，只有走代理才能访问。

What steps can reproduce the bug?

1.配置本地 HTTP 代理，并导出 HTTP_PROXY/HTTPS_PROXY。

2.执行：
curl -I https://www.youtube.com
curl -I https://www.google.com
结果正常（200 OK）。

3.在同一会话中，使用 FetchURL 工具访问 https://www.youtube.com 和 https://www.google.com。

4.观察到失败：Connection reset by peer。

What is the expected behavior?

FetchURL 应该读取 HTTP_PROXY/HTTPS_PROXY 环境变量，或者支持在 ~/.kimi/config.toml 中配置代理，从而像 curl 一样正常访问外网。

Additional information

当前临时 workaround：用 Shell 工具执行 curl/wget 代替 FetchURL。

本地代理为 Clash Verge 的 HTTP 代理，地址是 127.0.0.1:7890。

What version of Kimi Code CLI is running?

Which open platform/subscription were you using?

managed:kimi-code (Kimi Code account login)

Which model were you using?

K2.7 Code (kimi-for-coding)

What platform is your computer?

Linux 6.18.33.1-microsoft-standard-WSL2 x86_64 x86_64

What issue are you seeing?

In a network environment with GFW, the system proxy has been configured correctly, and curl in the Shell can access YouTube/Google normally, but the FetchURL tool will fail.

Shell environment variables:

HTTP_PROXY=http://127.0.0.1:7890
HTTPS_PROXY=http://127.0.0.1:7890
http_proxy=http://127.0.0.1:7890
https_proxy=http://127.0.0.1:7890
The curl test passes:

curl -I https://www.youtube.com # 200 OK
curl -I https://www.google.com # 200 OK
But FetchURL will fail when accessing the same URL.

Relevant logs in ~/.kimi/logs/kimi.log:

kimi_cli.tools.web.fetch:_fetch_with_service:158 - FetchURL service HTTP error: status=403, url=https://www.youtube.com
kimi_cli.tools.web.fetch:fetch_with_http_get:87 - FetchURL network error: Cannot connect to host www.youtube.com:443 ssl:default [Connection reset by peer], url=https://www.youtube.com
kimi_cli.tools.web.fetch:_fetch_with_service:158 - FetchURL service HTTP error: status=403, url=https://www.google.com
kimi_cli.tools.web.fetch:fetch_with_http_get:87 - FetchURL network error: Cannot connect to host www.google.com:443 ssl:default [Connection reset by peer], url=https://www.google.com
In addition, executing curl --noproxy "*" will return Connection reset by peer, indicating that the direct connection is indeed blocked and can only be accessed through a proxy.

What steps can reproduce the bug?

1. Configure the local HTTP proxy and export HTTP_PROXY/HTTPS_PROXY.

2. Execution:
   curl -I https://www.youtube.com
   curl -I https://www.google.com
   The result is normal (200 OK).

3. In the same session, use the FetchURL tool to visit https://www.youtube.com and https://www.google.com.

4. Failure observed: Connection reset by peer.

What is the expected behavior?

FetchURL should read the HTTP_PROXY/HTTPS_PROXY environment variable, or support configuring the proxy in ~/.kimi/config.toml to access the external network normally like curl.

Additional information

Current temporary workaround: Use shell tool to execute curl/wget instead of FetchURL.

The local proxy is Clash Verge’s HTTP proxy at 127.0.0.1:7890.
