I’m using SSH.net version 2024.0.0, but I cannot connect to an Ubuntu machine using openssh-server with a user certificate. However, I can connect using the command “ssh -i user-key username@host” in PowerShell. Does anyone have a problem like mine? thanks

private key format
—–BEGIN OPENSSH PRIVATE KEY—–
—–END OPENSSH PRIVATE KEY—–

I can connect using the command “ssh -i user-key username@host” and it works fine.
