Sorry I got busy with something else and didn’t make the time cut-off of this older thread.
It works sometimes, but get’s hung up periodically. But it’s doing something new, I’m assuming as a result of an attempted bug fix.
After going for a bit, it goes back to the prompt almost as if I never hit enter except it has listed out thoughts and explorations.
I keep retrying after it stops, it rarely starts working again.
It no longer hangs on ‘planning next moves’ or gives me the ‘taking longer than expected’.
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.
The network diagnostics look healthy. Looking at the message ID you shared, the request doesn’t appear to have reached our servers. This is consistent with a client-side issue we’ve identified where the chat can get into a stuck state between turns - specifically when the client thinks a previous generation is still active (when it’s actually already finished), new submissions get blocked silently.
This explains the behavior you’re describing: thoughts/explorations appear from a prior turn, but your new message never actually fires.
Workarounds until the fix ships:
When it happens: Open a new chat tab (Cmd+T in the chat panel) rather than retrying in the same one. The stuck state is per-tab.
If it recurs frequently in a session: Reload the window - Cmd+Shift+P > type “Reload Window” > Enter. This clears all stale state.
Pattern to avoid: If a response seems to stall or partially complete, give it a moment before sending a new message in the same tab. The deadlock is more likely to trigger when a new message is sent right after a turn that ended ambiguously.
Our team has identified the root cause and is tracking a fix. I’ll follow up when it ships.
