Hello @kevinn
I have completed additional troubleshooting and would like to share the results.
Additional investigation
-
I reinstalled Cursor, but the issue persists.
-
I also tested an older Cursor version, and the same issue occurs.
-
The issue occurs on both the desktop application and the web version.
-
The issue occurs when connected via VPN, on the corporate network, and also when using a mobile hotspot with VPN disabled.
-
Other users in the same organization are able to use Cursor normally.
-
Desktop Cursor launches successfully, but every chat request returns:
An unexpected error occurred. Request ID: e8c3cde7-94d2-4ecf-841c-78ccd71f073c
Network Diagnostics results
The following checks are successful:
- DNS
- Authentication
- Authentication UI
- Cursor Tab
- Agent Endpoint
- Codebase Indexing
- Downloads
- CDN
The following checks fail:
- API
- Ping
- Chat
- Agent
All failed checks report:
[internal] unable to get local issuer certificate
SSL Diagnostics reports:
Encrypted traffic is being intercepted by unrecognized certificate
Issuer:
O=Zscaler Inc.
CN=Zscaler Intermediate Root CA
The same result occurs even when using a mobile hotspot with VPN disconnected.
Given these findings, could you please advise whether Cursor recently changed any TLS or certificate validation behavior that might affect environments using Zscaler SSL inspection?
Also, since other users in the same company are able to use Cursor successfully, do you have any recommendations for identifying what difference on my machine could cause Cursor Chat traffic to fail while Authentication continues to work?
Thank you for your assistance.
