What's Wrong?

Bug: Claude Code crashes on first input in SSH-Remote session
OS: Windows 11 (PowerShell)
Node: v22.22.2 (downgraded from v24 per forum tip — didn't help)
Claude Code: v2.1.126
SSH Target: Hetzner Cloud Ubuntu 24.04
Workaround tried: Accepted ToS via CLI separately — didn't help
Reproducer: Connect via SSH-Remote, enter any text → crash

What Should Happen?

Claude Code should successfully connect via SSH-Remote to a remote
Linux server and remain stable when the user enters their first
prompt or interacts with the workspace.

Claude Code process exited with code 1

Steps to Reproduce

Environment

• OS: Windows 11
• Claude Code: v2.1.126
• Node.js: v22.22.2 (also reproduced with v24.15.0)
• npm: 10.9.7
• PowerShell: Windows PowerShell (default)

Steps to Reproduce

1. Install Node.js v22.22.2 from nodejs.org
2. Install Claude Code Desktop App for Windows
3. Generate SSH key locally:

ssh-keygen -t ed25519 -C "user@machine" -f $HOME\.ssh\id_ed25519 -N '""'

1. Copy public key (id_ed25519.pub) to remote Linux server's

~/.ssh/authorized_keys (or test via Hetzner Cloud Console)

1. Verify SSH works manually in PowerShell:

ssh root@<server-ip>
→ connects successfully, no password prompt

1. In Claude Code Desktop App, open SSH connection dialog:

• Name: "MyServer"
• SSH-Host: root@<server-ip>
• SSH-Port: 22 (or empty)
• Identity file: C:\Users\<user>\.ssh\id_ed25519

1. Click "Connect"
2. Accept "Trust this folder" prompt for the remote workspace
3. Optional: navigate to a project folder and select it
4. Type ANY text in the Claude prompt (e.g. "hello")
5. Press Enter

Actual Result

Claude Code process exits immediately with:
"Claude Code ist abgestürzt
Versuche, deine Nachricht erneut zu senden.
Claude Code process exited with code 1"

Workarounds Tried (none worked)

• Downgraded Node from v24.15.0 to v22.22.2 per

https://github.com/anthropics/claude-code/issues/<NR>
(forum post: "Workaround for me, just downgraded node from
24 to 22 and done!")

• Started claude CLI separately in PowerShell, accepted ToS,

exited cleanly. Then opened Desktop App SSH-Remote → still crashes.

• Restarted Claude Code Desktop App multiple times.
• Restarted Windows.
• Set ExecutionPolicy to RemoteSigned for current user.
• Verified MCP servers config — only built-in github MCP shows

"failed", but disabling/ignoring it doesn't help.

Notes

The CLI version (claude in terminal) starts and accepts input
without crashing — only the SSH-Remote feature in the Desktop
App crashes on first input.
