我宝塔添加PHP站点反代哪吒面板，配置文件(就是点击设置，然后左侧栏的配置文件，不是反向代理里面的配置文件)加上 
# upstream 配置
upstream dashboard {
keepalive 512;

nginx version: nginx/1.24.0
nginx: [emerg] duplicate upstream "dashboard" in /www/server/panel/vhost/nginx/nz.a.com.conf:63
nginx: configuration file /www/server/nginx/conf/nginx.conf test failed

# upstream 配置
upstream dashboard_v2 {
keepalive 512;
