更新加密后无法运行NginX

如何解决更新加密后无法运行NginX

我执行了以下操作来更新加密。

sudo systemctl stop ufw
sudo /etc/init.d/Nginx stop
cd /opt/letsencrypt
./letsencrypt-auto renew 
sudo systemctl start ufw
sudo /etc/init.d/Nginx start

当我在“ sudo systemctl start ufw”行中时，花了一段时间，而当我想运行“ sudo /etc/init.d/Nginx start”行时，我的连接丢失了。重新连接后，任何运行Nginx的尝试均失败，如下所示。我还重新启动了我的Droplet，但Nginx仍然无法运行。 我还应该提到，到目前为止，我已经使用当前的防火墙Nginx设置更新了几次。这是我第一次使用相同的设置遇到此问题。

感谢您的建议！

sudo /etc/init.d/Nginx开始 [....]（通过systemctl）启动Nginx：Nginx.service的Nginx.serviceJob失败，因为控制进程退出并显示错误代码。 有关详细信息，请参见“ systemctl status Nginx.service”和“ journalctl -xe”。
