nginx 代理 portainer 报 Unable to retrieve server settings and status

一、nginx配置

location /portainer {
    proxy_pass http://localhost:19000/;
    proxy_set_header Via "nginx";
    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 X-Forwarded-Port $server_port;
}

二、访问http://ip/portainer

}
