先跟各位道歉由於我是硬著頭皮上的網站，很多部份可能不懂，請多多包含……

我有個 VPS 上原本host一個 aaa.com，並且成功使用 letsencrypt 拿到 ssl 憑證，瀏覽器也是顯示secure
（然後，我可能不知道白目去改了什麼……）
總之，後來同個 server 上了 bbb.com, ccc.com，雖然也都有拿到 letsencrypt 的憑證
可是 http //bbb.com, http //ccc.com，能指向對的網站資料夾
https //bbb.com, https //ccc.com，卻會被導至 aaa.com 的網站資料夾
網址欄則是 https //bbb.com 顯示 insecure
請問我到底是改到了什麼，或我應該提供什麼各位檢視？才能讓 https //bbb.com, https //ccc.com 各自也去對的網站資料夾？

再求各位協助，土下座

這裡附上 apache2.conf 內容

這是 aaa.com 的 conf (在 site-enabled 資料夾裡)

        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName

        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerName aaa.com

這是 bbb.com 的 conf

=================

早上11點再度更新
嘆，我想應該是最一開始我在給 aaa.com 申請 ssl 時曾經參考過許多錯誤的教學（用各種方式申請失敗過很多次）
因此把整個設定給打亂了
apache 下 sites-available 資料夾裡面另外還有一個 default-ssl.conf 內容如下
不是很確定這個有沒有作用中

<IfModule mod_ssl.c>
        <VirtualHost _default_:443>
                ServerAdmin webmaster@localhost

                DocumentRoot /var/www/html

                # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

                # It is also possible to configure the loglevel for particular
                # modules, e.g.
                #LogLevel info ssl:warn

                ErrorLog ${APACHE_LOG_DIR}/error.log
                CustomLog ${APACHE_LOG_DIR}/access.log combined

                # For most configuration files from conf-available/, which are
                # enabled or disabled at a global level, it is possible to

                #   If both key and certificate are stored in the same file, only the
                #   SSLCertificateFile directive is needed.
                SSLCertificateFile      /etc/ssl/certs/ssl-cert-snakeoil.pem
                SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
                
                <FilesMatch "\.(cgi|shtml|phtml|php)$">
                                SSLOptions +StdEnvVars
                </FilesMatch>
                <Directory /usr/lib/cgi-bin>
                                SSLOptions +StdEnvVars
                </Directory>

        </VirtualHost>
</IfModule>

再補充一下，我查看了 etc 裡面 letsencrypt/live 的資料夾，確定三個domain都各有申請憑證（實際上command line 輸入 certbot 給三個 domain 申請/renew憑證也都會顯示「目前已經有了」）

所以我應該真的是如二樓大大所說，某個地方去設定到把 https 全部指到 aaa.com 的資料夾（雖然完全沒有印象）
我曾經去 google 過這麼做的方式，想要反向把它改回來
但但但但真的是毫無頭緒，才會上來求救…… orz
