[BUG] Offline mode while in VPN

Environment

• Platform (select one):
• [ ] Anthropic API
• [ x] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 0.2.104 (Claude Code)
• Operating System: RHEL8
• Terminal: warp

Bug Description

While running, cluade says Offline in bold red. The webfetch tool does not work. Additionally, most mcp servers return -32000 errors. Otherwise, claude code works fine.

Steps to Reproduce

1. Sign on to VPN.
2. start claude -- offline mode error occurs.
3. If run on mac with no VPN there is no offline error.

Expected Behavior

Not run in offline mode.

Actual Behavior

ran in offline mode.

Additional Context

Why does offline mode start in the first place? Is something trying to connect to an outside website? During an strace, I do see CC hanging when trying to connect to github. I try adding this to the no-proxy in my zshrc and or env before starting claude, but claude code does not respect the addition.

What else can I do to debug this?
