why ?

Hey, thanks for the report.

This is a known issue - the old cursor-server process on the remote host is blocking the new installation.

Fix - run on the remote Linux host:

pkill -f .cursor-server
rm -rf ~/.cursor-server /tmp/cursor-remote-lock.* /tmp/cursor-server-*.tar.gz

If 30 seconds isn’t enough for your network, add this to Cursor Settings (JSON):

"remote.SSH.connectTimeout": 120

Similar issue resolved here: Every time after the upgrade, Cursor Remote-SSH times out

Let me know if this helps.

  1. I clear remote server
    (base) root@DESKTOP-BE2FPE6:~# pkill -f .cursor-server
    (base) root@DESKTOP-BE2FPE6:~# rm -rf ~/.cursor-server /tmp/cursor-remote-lock.* /tmp/cursor-server-*.tar.gz

    set timout = 120S

    But still Error:
