Dreamweaver SFTP access

I've configured an AWS Transfer SFTP server and I tested the connection with FileZilla and macOS SFTP client. Both of them worked fine with public key authentication, but Dreamweaver drops error. The key has OpenSSH format and I generated it with ssh-keygen. Server info: 20.1 and 15211 build.

Error message: An FTP error occurred - cannot make connection to host. Your login or password incorrect.

Is there any workaround or solution to this error?
