I have one server try to connect a SFTP server by using Private Key and Username. it keeps ask me for the password. I noticed in the log the sever didn't offer key authentication. but we tested on the other machine, it worked. I also uninstall the WinSCP (select clear all configuration ) + delete all WinSCP related register key and files including temp files, and then reinstall it, it still didn't work.
Then my question is on the client sever, what would trigger the SFTP server not offering the key authentication methods?
