Add Folder to Workspace in a single-folder SSH window drops the connection: "Cannot reconnect. Please reload the window."#11941

Is there an existing issue for this bug?

  • I have searched the existing open issues and found none that apply.
  • If I find any issue of interest that is related or closed, I will included a link to it in this issue.

#10168 reports the same symptom (open since 2024, no cause identified). This report adds a minimal repro in a clean profile and what the logs show. #11805 and #11926 are related: the reconnect loop gives up on an error it does not recognise, but their triggers are different.

Required Troubleshooting Steps

  • I have read and performed the troubleshooting steps
  • I have tried both values of the remote.SSH.useLocalServer setting (both reproduce)
  • My issue was not covered in the Tips and Tricks
  • I will include a complete copy of my Remote - SSH logs

[Optional] Diagnose with Copilot

No, I did not ask @remote-ssh.

In step 2 of the troubleshooting wiki, what was the result of running the generated SSH command verbatim outside of VS Code?

Not applicable: the connection itself works. The window connects normally and breaks only when it switches from a folder to a workspace.

Environment

  • VS Code 1.145.0 (a717861c07586a53d83b80d742cd3f59b20a6273), Windows 11 Pro 10.0.26200 x64
  • Remote-SSH 0.128.0, remote.SSH.useExecServer: true, OpenSSH_for_Windows_9.5p2
  • Remote: Ubuntu 26.04.1 LTS x86_64, on the same LAN
  • Clean profile:
    • new --user-data-dir, --extensions-dir and --shared-data-dir
    • only Remote - SSH, Remote - SSH: Editing Configuration Files and Remote Explorer installed
    • settings: remote.SSH.serverInstallPath (a temporary path), remote.SSH.remotePlatform, security.workspace.trust.enabled: false

It also happens in my normal profile, with Workspace Trust on.

Steps To Reproduce

  1. Open a folder on an SSH host and wait until the window is connected: code --remote ssh-remote+linux-host /tmp/repro/A
  2. Add another folder from the same host: File > Add Folder to Workspace…, then pick /tmp/repro/B. code --remote ssh-remote+linux-host --add /tmp/repro/B does the same.

It reproduced in all 3 runs: remote.SSH.useLocalServer at its default (false), set to false, and set to true.

Expected Behavior

The window becomes an untitled multi-root workspace with both folders and stays connected.

Actual Behavior

The window hangs for about 20 seconds, then shows "Cannot reconnect. Please reload the window." It is then "Untitled (Workspace)" but disconnected.

What the logs show

  1. Adding a folder to a single-folder window switches it to a workspace in place, which stops the extension hosts. The local one exits at once (11:19:34.718 Extension host terminating: received terminate message from renderer).
  2. Remote-SSH had resolved the window's connection as a managed one (resolveAuthority(ssh-remote) returned 'Managed(1)'), and that connection is carried by Remote-SSH in the local extension host. From the moment that host exits, the management connection receives nothing.
  3. Reading the new workspace's configuration over that connection waits until the socket timeout 20 s later: received socket timeout event (reason: unacknowledgedMessage, unacknowledgedMsgCount: 2, timeSinceOldestUnacknowledgedMsg: 20004, …).
  4. The reconnect then runs while no extension host is up, so no resolver is registered. resolveAuthority(ssh-remote) fails after 0 ms with Cannot resolve authority, and the loop treats this as permanent: "An unknown error occurred while trying to reconnect, since this is an unknown case, it will be treated as a permanent error! Will give up now!" The new local extension host starts about 1.5 s later (11:19:56.392), too late.
  5. The server still had the connection and would have waited for it: [ManagementConnection] The client has disconnected, will wait for reconnection 3h before disposing...

So the switch to a workspace stops the very extension host that carries the remote connection, and the reconnect gives up before that host is back. Two possible fixes:

  • Keep the extension host that resolves a managed connection running across this switch, or restart it first.
  • Retry a Cannot resolve authority that comes while extension hosts are restarting, instead of treating it as permanent.

Workaround

Open the folders as a saved workspace first: create a .code-workspace file on the host and use File > Open Workspace from File…. Adding folders to a workspace that is already open only updates that file and does not restart the extension hosts, so the window stays connected. I verified this in the same clean profile.
