在宝塔V8.0.5版本，反向代理配置代码需要更新，不然会出现：502 Bad Gateway

#PROXY-START/

location ^~ /
{
    proxy_pass http://127.0.0.1:20108;
    proxy_http_version 1.1;
    proxy_read_timeout 360s;   
    proxy_redirect off; 
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;

    add_header X-Cache $upstream_cache_status;

    #Set Nginx Cache


    set $static_fileLzXnun8E 0;
    if ( $uri ~* "\.(gif|png|jpg|css|js|woff|woff2)$" )
    {
     set $static_fileLzXnun8E 1;
     expires 12h;
        }
    if ( $static_fileLzXnun8E = 0 )
    {
    add_header Cache-Control no-cache;
    }
}

#PROXY-END/

反向代理这段配置需要更新，不然在宝塔面板V8.0.5版本会提示：502 Bad Gateway 运行不起来。 高手帮忙更新一下代码。
