Cursor connection problem with agent.api5.cursor.sh

Hey, thanks for the report. The getaddrinfo ENOTFOUND agent.api5.cursor.sh error means there’s a DNS resolution issue. This is a known problem caused by a misconfigured SSL setup on the Cloudflare CDN.

For now, please try:

  • Change your DNS to Cloudflare (1.1.1.1 / 1.0.0.1) or Quad9 (149.112.112.112) in your network settings. Google DNS 8.8.8.8 can route to an incorrect Cloudflare CDN IP.
  • Toggle your VPN on or off. In the Jan 8 thread, this fixed it for some users.
  • Try a different network, like a mobile hotspot.
  • In Cursor, go to Settings > Network and switch from HTTP/2 to HTTP/1.1 or HTTP/1.0.

Please keep an eye on updates in the linked thread.
