Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. These SSH errors are often caused by stuck lock files or a broken server install.

Try this:

On the remote Linux host, run:

killall bash
rm -rf ~/.cursor-server /tmp/cursor-remote-lock.* /tmp/cursor-server-*.tar.gz

Then in Cursor, add this to Settings (JSON):

"remote.SSH.connectTimeout": 120

A similar fix helped in this thread: Connecting to Remote-SSH always fails

If the issue still happens, can you share the full logs from the Remote-SSH panel (View > Output > select Remote-SSH in the dropdown)? That should help pinpoint the cause.

Thank you, but I have the same ussue afrer putting your recomendation.

Thanks for the logs, I can see the issue now.

Your Windows username contains Cyrillic characters (КП), and SSH can’t reliably resolve the key path. In the logs you can see:

no such identity: C:\Users\\320\\232\\320\\237\.ssh\id_ed25519

Please create your SSH keys in a folder without Cyrillic characters (for example C:\ssh-keys), then point to that key in ~\.ssh\config.

This is a known limitation. Non-Latin paths on Windows can cause issues with SSH tooling. Let me know if this fixes it.

at async c:\Users\КП.cursor\extensions\anysphere.remote-ssh-1.0.36\dist\main.js:2:407565] I wanted to reinstall Cursor on the C drive, but Windows has a system “Users” (Пользователи) folder, so the installation goes directly to it, and it’s in Cyrillic. It won’t let me rename it. As far as I understand, this is the whole problem. Nothing helps.

Thanks for the info. Cursor installs extensions under .cursor in your user folder, and Cyrillic characters in the path can break SSH.

The most reliable fix is to create a new Windows user with a Latin-only name and work from that account.
