Cursor errors / Connectivity

Connection failed. If the problem persists, please check your internet connection or VPN

platform: Cursor / category: Connectivity

Cause

Cursor cannot reach its backend API servers, most often because a VPN, corporate proxy, or firewall is intercepting or blocking the TLS connection.

Fix

Disconnect the VPN and retry. In Settings search 'HTTP/2' and enable 'Disable HTTP/2', then restart. Behind a corporate proxy, set the proxy under Settings > Network Proxy and whitelist api2.cursor.sh. Check Cursor's status page for incidents.
