Add HTTP Proxy support

I'm also facing the same issue with claude-code failing behind an HTTP proxy. I've tried using proxychains4 to route its traffic through the proxy, but that didn't work.

I've confirmed that proxychains4 works with other applications. I'm wondering if this is a intended behavior.

I am also facing same issue. It is failing behind corporate firewall and I have found no docs or way to connect. I can definitely get it to work on my personal pc. This is on a mac. I get error oauth failed, with very little diagnostics.

Thank you for the suggestion! the latest version now supports setting HTTPS_PROXY env var

What is this "latest version"? I intall the version 0.2.36 (Claude Code) today, I have the HTTPS_PROXY env var in the shell (zsh) and still I get

 Unable to connect to Anthropic services

 Please check your internet connection and network settings.

@levpopov Claude Code 0.2.44 uses HTTPS_PROXY for itself but NOT for the API, so it still doesn’t work.

 What's new:

  • Ask Claude to make a plan with thinking mode: just say 'think' or 'think harder' or even 'ultrathink'
  • MCP server startup timeout can now be configured via MCP_TIMEOUT environment variable
  • MCP server startup no longer blocks the app from starting up
  • New /release-notes command lets you view release notes at any time
  • `claude config add/remove` commands now accept multiple values separated by commas or spaces
