为啥https会自动301跳转到http？

Question

有个站点，刚刚成功的安装了 Let’s Encrypt 的免费证书，nginx已经配置了关于https的访问。

现在可以通过 https 和 http 两种方式访问了，有些页面两种方式都可以访问，但是部分页面通过https访问竟然会 301 跳转到 http 页面地址，例如：

https://www.phpernote.com/php-template/200.html

这是为什么呢？请各位大神各抒己见，多谢！

nginx 配置如下：

server {
        listen       80;
        server_name  www.phpernote.com ;
        root   /home/xxx/xxx;
        location / {
            index  index.php index.html;
        }
        include /home/xxx/xxx/.htaccess;
        location ~ ^(?:(?<!\.php).)+\.php($|/.*) {
            fastcgi_pass unix:/tmp/php-cgi.sock;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

server {
        listen       80;
        server_name  phpernote.com ;
        root   /home/xxx/xxx;
        location / {
            index  index.php index.html;
        }
        include /home/xxx/xxx/.htaccess;
        location ~ ^(?:(?<!\.php).)+\.php($|/.*) {
            fastcgi_pass unix:/tmp/php-cgi.sock;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

server {
        listen       443 ssl;
        ssl on;
        ssl_certificate /etc/letsencrypt/live/www.phpernote.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/www.phpernote.com/privkey.pem;
        server_name  www.phpernote.com ;
        root   /home/xxx/xxx;
        location / {
            index  index.php index.html;
        }
        include /home/xxx/xxx/.htaccess;
        location ~ ^(?:(?<!\.php).)+\.php($|/.*) {
            fastcgi_pass unix:/tmp/php-cgi.sock;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

配置信息应该没问题，
include /home/xxx/xxx/.htaccess;
这里有什么特殊的配置？

更改配置后有 重启nginx 么
