我正在开发网上商店，并且在本地计算机上一切正常。客户将商品添加到购物车，输入他的凭据，然后单击“下订单”，然后将订单确认发送到他的电子邮件中。即使使用redis + celery，它也可以正常工作，但是由于我将项目部署到服务器（linode.com）后，订单确认不起作用。工人承担了任务，但从不执行。我以为是芹菜引起的，所以我决定不使用任务管理器和队列就发送电子邮件。但这没有帮助。
我在服务器中使用UFW防火墙：
To Action From
-- ------ ----
22/tcp ALLOW Anywhere
80/tcp ALLOW Anywhere
Anywhere ALLOW 96.126.119.66
443 ALLOW Anywhere
22/tcp (v6) ALLOW Anywhere (v6)
80/tcp (v6) ALLOW Anywhere (v6)
443 (v6) ALLOW Anywhere (v6)
我收到这样的错误：
[Errno 110]连接超时
希望你能帮助我理解这个问题
