Try to with this function, I think that your parameters are not ok, try fullfilling this key only a string

  def self.upload_xml(file)
    Net::SFTP.start(
      "ip",
      "user",
      #password: "password", is a comment
      key_data: [],
      keys: "/private/key/path/rsa_file",
      keys_only: true,
      verify_host_key: false
    ) do |sftp|
      # do your things for example upload a file
      sftp.upload!(file.document.path,
                   file.document.original_filename)
    end
  end

and the configuration, the path to your private key should be and absolute path,

also try/verify your private rsa file:

$sftp -i .ssh/ssh-2-rsa user@sftp.ip.net
