What's Wrong?

My app needs to have no proxy to work.
If I do this in ~/.claude/settings.json

{
  "env": {
    "ANTHROPIC_BASE_URL": "<base-url>",
    "ANTHROPIC_AUTH_TOKEN": "<token>",
    "CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS": "1",
    "CLAUDE_CODE_TELEMETRY_DISABLED": "1",
    "https_proxy": "",
    "HTTP_PROXY": "",
    "http_proxy": "",
    "HTTPS_PROXY": ""
  },
  "model": "haiku"
}

Claude blocks. It takes the proxy that is in my bashrc.

Now, if I do this:

HTTPS_PROXY="" HTTP_PROXY="" https_proxy="" http_proxy="" claude

Claude works.
I should note that I tried NO_PROXY="*", and it doesn't work.

What Should Happen?

Claude should be able to reach my base URL without a proxy, just like it does when we pass proxy arguments with the command.

Error Messages/Logs

❯ bonjour
⎿  API Error: Connection error. (after several minutes)

Steps to Reproduce

Prerequisites:

A proxy is configured in your system bashrc (e.g., export https_proxy=...)
Your API URL works without the proxy (e.g., curl --proxy "" https://<base-url> succeeds)

Test 1 - settings.json (FAILS):

{
  "env": {
    "ANTHROPIC_BASE_URL": "<base-url>",
    "https_proxy": "",
    "HTTP_PROXY": "",
    "http_proxy": "",
    "HTTPS_PROXY": ""
  }
}

Result: Claude blocks

Test 2 - CLI (WORKS):

HTTPS_PROXY="" HTTP_PROXY="" https_proxy="" http_proxy="" claude

Result: Claude connects successfully

Expected: Both methods should work the same way.

Ok I installed claude from the binary. Maybe the is the problem.. I'm ready to close exept if someone confirms the bug with others installs ?

I will try with npm later and if yes, it's a duplicate of https://github.com/anthropics/claude-code/issues/14165

Confirming I am seeing this as well. Regardless of how it is provided (bash env or settings.json env) versions newer than 2.1.22 do not honor NO_PROXY.

Do you have Claude's installation via the binary? Or npm ?

This is the binary install. It is affecting everyone on our team.

The issue is still present with the recently released 2.1.29, FYI.

ok thanks for your reply @bhilton
So for now the workaround is to run claude with env vars in the command directly

HTTPS_PROXY="" HTTP_PROXY="" https_proxy="" http_proxy="" NO_PROXY="*" claude

Sorry, I think this Issue may be discussing two different problems.

settings.json may not support disabling proxy settings such as HTTP_PROXY by setting them to the empty string (not an issue that is affecting me, but may be real)
NO_PROXY does not work anymore regardless of how I supply it (env var, settings.json, direct from the cli as you typed - which is actually just setting an env var anyway). Our team has had to remain on 2.1.22 in order to use NO_PROXY.

Are people still seeing this on 2.1.38+?

2.1.38 fixed one proxy issue for me but I still need to set env variables before running the Claude binary to ensure everything works.

I think the problem is that some underlying libraries will read the proxy variables when Claude starts up and those libraries are not impacted by the changes that Claude Code makes based on the settings.json envs. They already set their internal variables for the proxy and won't reload from the environment.

I don't have this problem anymore (claude 2.1.62)
