Windows WSL2 consistent API Errors

Issue overview

Hello, I have installed Claude code on my Windows Laptop using WSL following: https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview. I was able to get claude installed fine, no errors but I keep getting an API Error that I havent been able to decipher. My API Keys are created and I see them at https://console.anthropic.com/. Billing is set up as well. The error below is consistent on ALL calls including /login

Error:

 Tips for getting started:

 1. Run /init to create a CLAUDE.md file with instructions for Claude.
 2. Ask Claude questions about your codebase.
 3. Ask Claude to implement changes to your codebase.

Fixes tried / Verifications done

• Reinstall Claude multiple times.
• Deleted API Keys & recreated them multiple times.

• Verified claude.json to see hasCompletedOnboarding:true & hasTrustDialogAccepted:true & customerApiKeyResponses:approved.
• Verified System status was UP: https://status.anthropic.com/
• Used sudo npm install instead or npm install.
