Thank you cursor team for making the remote tunnel available! Really appreciate you listening to the voice of customers.

I encountered an issue with this feature. Here is the steps:

1. I installed remote development extension on cursor
2. On my remote instance: I ran this code:

```auto
  curl -Lk 'https://code.visualstudio.com/sha/download?build=stable&os=cli-alpine-x64' --output vscode_cli.tar.gz && tar -xf vscode_cli.tar.gz && ./code tunne

```

1. Then I go back to VScode, clicked on remote explorer on the left, and saw the running tunnel.
2. I tried to connect to it. but an error appeared  
On cursor:

```auto
Failed to connect to the remote extension host server (Error: Connection error: Client refused: version mismatch)

```

On remote instance:

```auto
Disposed of connection to running server
warn [rpc.14] error handling call: NoAttachedServerError(NoAttachedServerError)

```

**Software versions**

**Replicating on VSCode**  
I replicated the steps above on VSCode v1.89 and 1.90. I did not have such issues.

Any suggestions?

You will want to use this download URL:

[https://api2.cursor.sh/updates/download-latest?os=cli-alpine-x64](https://api2.cursor.sh/updates/download-latest?os=cli-alpine-x64)  
Then run ./cursor (rather than ./code)

Then try connecting

Hi, would someone mind explaining this issue? (@amanrs ?)

it’s necessary to run a “cursor” remote server instead of a vscode one?

Is this specified somewhere in the docs? How did people find out about this URL?
