Hey, thanks for the report.

This looks like a known issue affecting certain regions since Dec 29. The symptoms are identical: simple prompts work, but certain content or long requests fail across all models.

To help narrow it down, we need a bit more info:

1. Region: What region/country are you in?

2. Console errors: Go to Help \> Toggle Developer Tools \> Console, reproduce the issue, and send a screenshot of the red errors.

3. New Request ID: After the error, copy the Request ID (Chat menu \> Copy Request ID).

4. Network: Are you using a VPN or proxy?

In the meantime, please try:

1. Change DNS:

2. Disable HTTP/2:

- ["Connection Error" needs to give us more information](https://forum.cursor.com/t/connection-error-needs-to-give-us-more-information/147677)

Send the requested info and I’ll pass it to the team with priority right away.
