Hi @efengshan, EPERM likely indicates that antirvirus (such as Windows Defender) prevented Cursor from establishing the connection. Can you check to see if any files were quarantined or blocked?

I solve this problem by degrading my extension “Remote-SSH“ to an earlier version。 Thanks for your reply。
