Cursor errors / Connectivity

AI features broken: ECONNRESET stuck on local proxy 127.0.0.1

platform: Cursor / category: Connectivity / code: ECONNRESET

Cause

Cursor's traffic is intercepted by a local proxy (Clash, v2ray) on localhost that resets the TCP connection, blocking all AI API calls.

Fix

Pause or exit the local proxy and restart Cursor to test recovery. In Settings, enable 'Disable HTTP/2' and restart. If the proxy is required, point Cursor's network proxy setting at the correct address rather than relying on system-wide interception. Check the proxy logs for TLS inspection/cert pinning blocking Cursor.
