Answer

In the error message the supported host key algorithms of both TurboFTP client and remote SSH server are shown (see below for example). If the SSH server supports ssh-rsa and ssh-dss algos while TurboFTP doesn't, you can enable them in Site Settings -> SFTP -> Host key algorithms. They are by default disabled due to low crypto strength. It is suggested to use stronger algorithm to reduce risk.

ERROR-0:> selecting hostkey algorithm: no matching hostkey algo, client: rsa-sha2-512,rsa-sha2-256,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, server: ssh-dss,ssh-rsa (error #33)
