Dear Cursor Team,

I hope this message finds you well. I have been using Cursor for coding, but recently, I often encounter the error message “Connection failed. If the problem persists, please check your internet connection or VPN.”

Request ID: ecd84bf5-558a-4e7b-a707-cf7037a81356

I have thoroughly checked my internet connection and VPN (when applicable), and they are functioning properly. I am wondering whether this is a short - term glitch in the system or if there have been long - term policy changes regarding connections, such as potential restrictions.

This information is crucial for me as it will help me decide whether to continue using Cursor for my coding needs.

Thank you in advance for your attention to this matter and for providing clarification.

Best regards

Is my understanding correct that the provided computing power or service access capability cannot meet the actual usage demand?

Hey, thanks for the report. This is a known connection issue. Please try the following:

  1. Disable HTTP/2 (most common fix):

    • Open Cursor Settings with CMD/CTRL+,
    • Search for “HTTP/2”
    • Enable “Disable HTTP/2”
    • Restart Cursor

  2. Run network diagnostics:

    • Cursor Settings → Network → Run Diagnostics
    • Share the results if the issue persists

This helps most users on networks with partial HTTP/2 support. Reference: Constant connection error

Let me know if this helped.
