Network realities in regulated environments
Use the lesson to respond to this. "An enterprise admin reports: 'Half our developers can use Chat and Agent, the other half just get errors. Same version, same company.' What's your hypothesis order?" Keep the answer plain.
Step 1 of 2
Network realities in regulated environments
Cursor's AI features have to reach Anysphere's services, so a corporate proxy, a firewall or an air-gapped network can break them while the editor stays healthy.
- Network condition
- Corporate proxy
- Typical symptom
- Requests time out or fail with TLS errors
- Where to point
- Proxy allowlist and proxy settings in the editor/OS
- Network condition
- Firewall / allowlist
- Typical symptom
- AI features dead, editor fine
- Where to point
- Required Cursor/Anysphere endpoints not allowlisted
- Network condition
- Air-gapped / regulated
- Typical symptom
- No outbound AI calls possible
- Where to point
- Deployment options and admin discussion; not a client bug
| Network condition | Typical symptom | Where to point |
|---|---|---|
| Corporate proxy | Requests time out or fail with TLS errors | Proxy allowlist and proxy settings in the editor/OS |
| Firewall / allowlist | AI features dead, editor fine | Required Cursor/Anysphere endpoints not allowlisted |
| Air-gapped / regulated | No outbound AI calls possible | Deployment options and admin discussion; not a client bug |
Editor works but AI doesn't is the classic network-not-product signature.
In the cross-functional round, show you triage the type of issue, not just the issue: "This is a config question, so I route it to the admin and our docs; this one reproduces on a clean network, so it's a real bug and I write the repro for Eng."
Demonstrating that you protect Engineering's time by filtering confusion from defects is exactly the support-scaling instinct Cursor hires for.
"Good news: the editor itself is healthy, and the AI calls are being blocked before they leave your network. That points at the proxy or firewall rather than Cursor. Can you confirm with your IT admin that our endpoints are allowlisted? I'll send the exact list so the change is quick."
