Does this stop you from using Cursor

Yes - Cursor is unusable

Hey there.

First things first, I’d suggest upgrading to 2.2 to rule out any issues with this specific version.

It would be good to remove Cursor from the equation and try some network calls from the command line.

$headers = @{
    "Content-Type" = "application/json"
    "Connect-Protocol-Version" = "1"
}
Invoke-WebRequest -Uri "https://api2.cursor.sh/aiserver.v1.NetworkService/IsConnected" `
    -Method POST `
    -Headers $headers `
    -Body "{}" `
    -UseBasicParsing

Is this successfull, or still failing?

You are right. It’s a problem with my internet connection. I got an error in the console :frowning:
