我的服务器在端口 443 上运行良好,但现在它没有运行。
服务器是:Contabo VPS,Ubuntu 22.04
包含 nginx、iRedMail
使用命令sof -i -P -n | grep LISTEN
,我得到:
nginx 3124 root 6u IPv4 39437 0t0 TCP *:443 (LISTEN)
nginx 3124 root 7u IPv4 39438 0t0 TCP *:80 (LISTEN)
nginx 3125 www-data 6u IPv4 39437 0t0 TCP *:443 (LISTEN)
nginx 3125 www-data 7u IPv4 39438 0t0 TCP *:80 (LISTEN)
并ufw status

使用命令从客户端检查nmap -P0 mydomain.com
