我正在AWS Ubuntu实例上运行Rails服务器。我正在尝试从Windows桌面上的浏览器访问服务器。直到昨天,这一直工作得很好。从昨天开始,我开始在浏览器上显示空白页面,并显示以下消息:

This site can’t be reached The webpage at http://10.110.104.76:3000/ might be temporarily down or it may have moved permanently to a new web address.
ERR_CONNECTION_ABORTED

这是我启动Rails服务器时看到的:

rails s
=> Booting Puma
=> Rails 5.0.7.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
Puma starting in single mode...
* Version 3.12.0 (ruby 2.4.4-p296), codename: Llamas in Pajamas
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://0.0.0.0:3000
Use Ctrl-C to stop

我完全感到困惑-为什么这几个月来一切正常,从昨天开始突然停止工作?请帮忙!

我什至尝试跑步

sudo ufw allow 3000

允许端口访问端口3000但没有运气!

使用IP启动rails时,出现以下错误:

rails s -b 10-110-104-76
=> Booting Puma
=> Rails 5.0.7.1 application starting in development on http://10-110-104-76:3000
