Hey, thanks for the report. I see the screenshot with “Connection failed. Please try again…” This is a generic client-side error that shows up when Cursor can’t reach the backend. On our server logs, there were no errors at the time of your report, so this looks more like a network issue, not a bug specific to debug mode.
To dig deeper, I need a bit more info:
Does this happen every time in debug mode, or was it a one-off? Does it reproduce in the normal chat too?
The Request ID from the latest failure. Open the chat menu (three dots in the top right) > Copy Request ID.
Are you using a VPN, a corporate network, or a proxy like Zscaler?
In the meantime, please try a couple things:
Network Diagnostics: Cursor Settings > Network > Run Diagnostics. This will show which endpoints you can’t reach.
Disable HTTP/2: open App Settings Ctrl+,, search for HTTP/2, and turn on Disable HTTP/2. This often helps on corporate networks and with proxies.
