Following up from your earlier thread where @deanrie asked for more details. Thanks for the version info and request IDs here.
This is something we’ve been seeing across multiple users, and your description of the behavior changing (no longer showing “Taking longer than expected” but instead silently returning to the prompt) is consistent with reports we’re tracking. Our team is actively investigating.
To help narrow down what’s happening on your end, could you share two things?
-
Network diagnostics: Cursor Settings > Network > Run Diagnostics, then click “Copy diagnostics” and paste the results here. This checks whether your network setup (proxy, VPN, firewall) is affecting the streaming connection.
-
A per-message request ID from a failed chat: When the chat “goes back to the prompt” after showing thoughts, click the three-dot menu (…) on the last message that appeared, then Copy Request ID. The IDs you shared are conversation-level IDs, which we can work with, but a per-message ID gives us more precise server-side data.
Also, as a quick workaround, try adding this to your settings: open Settings (Cmd+,), search for HTTP/2, and enable Disable HTTP/2. Some users have seen improvement with HTTP/1.1 for streaming reliability.
Let me know how it goes.
