What's Wrong?
Environment:
Claude Code CLI v2.1.201
macOS
No VPN, no proxy, home wifi
Project: local Next.js/Python repo
Symptom 1 — Fresh sessions (claude, no flags):
Connects and works normally for roughly 2–3 exchanges, then every subsequent message fails with:
API Error: Unable to connect to API (ECONNRESET)
Symptom 2 — claude --resume:
Fails immediately, every time, before any message can be sent. Same ECONNRESET error, but occurs at connection/startup rather than mid-session.
Troubleshooting already performed:
Full claude auth logout / claude auth login — no change to either symptom
Confirmed all MCP connectors (Drive, Calendar, Gmail, IBKR) disconnected and re-synced cleanly via claude mcp list
Disabled MCP entirely via --strict-mcp-config --mcp-config '{"mcpServers":{}}' — issue persisted
Full process kill (pkill -f claude) and relaunch — no change
VPN toggled on/off — no change
Wifi reset, router reboot attempted — no change
node -e "https.get('https://api.anthropic.com', ...)" returns clean 404 — confirms basic network path is healthy
Anthropic status page shows all systems operational
What Should Happen?
Expected: Fresh sessions should hold a stable connection; --resume should reconnect and load prior session state.
Actual: Fresh sessions drop after ~2-3 turns; --resume cannot connect at all.
