Current Behavior

I am trying to connect to my workspace using the VSC Desktop application (Mac). I see my workspaces through the coder extension and the following ssh config is generated:

# --- START CODER VSCODE my.domain.com ---
Host coder-vscode.my.domain.com--*
  ConnectTimeout 0
  LogLevel ERROR
  ProxyCommand "/Users/myuser/Library/Application Support/Code/User/globalStorage/coder.coder-remote/my.domain.com/bin/coder-darwin-arm64" --global-config "/Users/myuser/Library/Application Support/Code/User/globalStorage/coder.coder-remote/my.domain.com" ssh --stdio --usage-app=vscode --disable-autostart --network-info-dir "/Users/myuser/Library/Application Support/Code/User/globalStorage/coder.coder-remote/net" --ssh-host-prefix coder-vscode.my.domain.com--  %h
  SetEnv  CODER_SSH_SESSION_TYPE=vscode
  StrictHostKeyChecking no
  UserKnownHostsFile /dev/null
# --- END CODER VSCODE my.domain.com ---

The above config tries to access /api/v2/users/me/workspace/myuser--24-hours?include_deleted=false (24-hours being my workspace).

To debug, I replaced "%h" in the ssh config with "myuser--24-hours". This resulted in access to the following URL: /api/v2/users/myuser/workspace/24-hours?include_deleted=false. This will work, but of course the config will be overwritten on the next attempt.

Relevant Log Output

Exec server for ssh-remote+coder-vscode.my.domain.com--myuser--24-hours failed: Error

Expected Behavior

Opening the Workspace by clicking "VS Code Desktop" in the UI.

Steps to Reproduce

1. Create a workspace "24-hours"
2. Wait till it's ready
3. Click "VS Code Desktop"

Environment

• Host OS: Rocky 9.6 (where Coder runs)
• Coder version: v2.24.2+0ead64f
• Workspace OS: Ubuntu 24.04.2
• Client OS running VSC: macOS 15.5 (24F74)
