使用cron选项卡发送邮件时连接拒绝

我每天都在使用gem来发送电子邮件任务。 我在RAKEFILE名称coffee中创建了一个rake任务。 这是我的任务代码：

 task :coffee => :environment do ReservationBooksNotify.notify.deliver puts "hihi" end 

当我在控制台rake coffee运行此任务时，它工作正常！ 但是当我在schedule.rb中创建一个计划以便每分钟自动发送邮件时，我收到一个错误

hihi rake流产！ 连接被拒绝 – 连接（2）

跟踪时的错误

我的schedule.rb（在/ config中）

 set :output, "~/Working/whenever.log" every 2.minutes do rake 'coffee' end 

我认为我的邮件程序配置没有问题，因为它在我在控制器和控制台中发送邮件时有效。 请帮帮我，谢谢！

最后，我不知道为什么，我尝试rake assets: precompile ，然后重启服务器，一切正常！
