create action on controller save method, else statement doesn't work?

It successfully creates a server but the problem is it doesn't proceed to the else statement if it doesn't save.

servers_controller.rb

def create
@server = Server.new(server_params)
  if @server.save
    flash[:sucess] = "Server created successfully!"
    redirect_to servers_path
  else
    render 'new'
  end
end

_form.html.erb

<div class="jumbotron">
<%= bootstrap_form_for @server do |f| %>
  <%= f.text_field :name, required: true %>
  <%= f.text_field :ip_address, label: "Ip Address", required: true  %>
  <%= f.select :database_name, options_for_select(@db_names), label: "Current Databases:" %>
  <%= f.submit %>
<% end %>
</div>
