SSH into Linux works on VS Code but not Cursor

Bug Report
1

I have a SSH Config with multiple instances. I can connect to some remote instances but not others using Cursor. But the same config works with VS Code.

I have tried reinstalling Cursor. I rebooted VM, and put new SSH keys on the host.

Running Cursor on M3 Mac. It’s weird that it works on some instances but not others.

Could be a SSH server config issue, but I’m able to get VS Code to connect to it.

Both KEY1.cer and cursor.pem pub keys are in ~/.ssh/authorized_keys on the host I’m trying to connect to.

SSH Config:

Host HOSTNAME
  HostName <IP_ADDRESS>
  User ec2-user
  IdentityFile ~/.ssh/cursor.pem

Instance is running Amazon Linux2

I have the same issue. Just wrote about it at Error connecting to Remote SSH · Issue #1027 · getcursor/cursor · GitHub
Anyone knows a workaround?
