Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

On Fedora 43 Cursor app works while CLI does not. Agent is able to login but then there is no reply to prompts, I only see endless reconnect attempts. I am behind corporate Zscaler VPN but Cursor IDE works fine so thats not the issue here. I ve followed many debugging leads like adding “useHttp1ForAgent”: true in cli-config.json but nothing seems to work. Running agent with --debug also does not reveal much, can attach that output if necessary. Plz support

Steps to Reproduce

Run “agent” on linux terminal.

Expected Behavior

Run “agent” on linux terminal can be prompted and reply as a normal agent.

Yes - Cursor is unusable

Hi @TSk!

If you’re behind ZScaler, very likely you need to add ZScaler certs to NODE_EXTRA_CA_CERTS as documented here.

You can test to see if it’s an SSL issue by running agent -k (which disables SSL/TLS certificate verification), but this is not a good solution for production use of the CLI!
