Cursor gets practically stuck after the first couple of prompts in a brand new chat with a small context window. See sample chat, everything seems greyed out and it just stops responding. I am on the ultra plan. ![Screenshot 2026-01-15 at 5.23.57 PM](https://us1.discourse-cdn.com/cursor1/original/3X/e/9/e902c7bee80adea4ec39e735ad5bebfd11f83100.png) ---

I’m jumping in to say I am experiencing very similar performance issues today, though with a slightly different technical profile. While my UI isn’t necessarily greying out, the **Agent/Composer** is stalling approximately 90% of the time during the “planning next moves” stage. **My Experience Today:** - **Stalling:** Using Auto Mode almost always leads to an indefinite hang during planning. - **Intermittent Success:** Static models sometimes work for 1 or 2 turns before failing again. - **Connectivity Tests:** Interestingly, all of Cursor’s internal network connectivity tests pass with a checkmark for me. **Technical Details from my Logs:** Despite the successful connectivity tests, my logs are showing severe transport errors that seem to be causing these hangs: - **Socket Disconnections:** Frequent `ConnectError: [aborted] Client network socket disconnected before secure TLS connection was established` . - **Streaming Timeouts:** Repeated warnings stating “No first token received within 2s… 16s… 32s” . - **System Errors:** Specific **`ECONNRESET`** codes appearing during calls to `checkQueuePosition` and `getTeamPrivacyModeForced` . It feels like there might be a broader issue with the streaming backend or how TLS handshakes are being handled today, especially since standard connectivity checks don’t catch it. **Environment:** Version 2.3.35 on Windows (win32 x64). Is anyone else seeing these specific `ECONNRESET` or “No first token received” errors in their developer logs (Help \> Toggle Developer Tools)? ---

Hey, thanks for the report and the detailed logs. This looks like a server or network issue with streaming. The ECONNRESET and “No first token received” errors point to the connection getting dropped. As a workaround, try this: - Settings \> Cursor Settings \> search for “HTTP/2” \> enable “Disable HTTP/2” - Restart Cursor @Kris_B, can you share your Cursor version (Help \> About Cursor) and the Request ID (chat menu in the top right \> Copy Request ID)? If you’re using a VPN or a corporate network, try turning it off temporarily. It often affects streaming connections. ---

Got an update today that fixed it. `2.3.41` 😭 ---

For me, restarting my mac and picking a new chat agent worked. ---
