Apache2 无法启动腻子 AWS Windows

Question

I am trying to start a django project using an AWS EC2 linux server using putty on windows, however Apache2 is showing an error related to the fact that the address is already used as shown in the next code:

apache2.service - The Apache HTTP Server
Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Sat 2020-07-25 19:51:59 UTC; 2min 7s ago

我已经尝试使用下一个代码验证网络的状态，但失败仍然相同。

systemctl status apache2.service

我还尝试使用下一个代码验证服务监听端口，output 是：

bitnami@ip-172-31-4-25:~$ sudo netstat -ntlp | grep 80
tcp6       0      0 :::80                   :::*                    LISTEN      15122/httpd

我将不胜感激任何建议。

检查Skype，如果它正在运行则先关闭然后启动Apache服务。 Skype 也使用端口 80。
