15.0：

默认安装，使用80端口，通过宝塔配置代理外网443，内外网都可以正常登录

配置如下：

server
{
    listen 443 ssl http2;
    server_name zt.xxx.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/zt.xxx.com;

    ssl_session_timeout 10m;
    error_page 497  https://$host$request_uri;

    error_page 404 /404.html;
    error_page 502 /502.html;
 
        location ~ /purge(/.*) {

升级到18.10后，内网可以正常使用，外网可以打开登录页面，但点击登录没有反应
