Subject: Unable to Use Cursor Due to Repeated “connect error” in Streaming CPP

Message:

Hello, I’m a Cursor user from China. Recently, I’ve been completely unable to use Cursor due to a persistent error. The software continuously outputs the following logs and then stops working:

I’m using a home network in China with internet access via a proxy. Specifically, I’m using Clash for Windows as the proxy tool. The connection to Cursor is intermittent—it works briefly and then fails most of the time.

Please help me investigate and fix this issue. Thanks in advance!

Hey, try disabling HTTP2 in the settings. To do this, go to the settings using the shortcut Ctrl + , find the Disable HTTP2 option, and enable it. Hopefully, this will help.
