错误请求400:nginx运行状况检查/状态

我正在对我的nginx服务器进行健康检查，我一直在使用它

不同的状态，它应该只返回200，但它通过以下400个错误请求保持

10.10.25.2--[19/Jun/2014:13:55:06+0400]“GET/status/HTTP/1.0”200-00 10.10.25.3--[19/Jun/2014:13:55:07+0400]“GET/status/HTTP/1.0”200 0“-” 10.10.25.2--[19/Jun/2014:13:55:08+0400]“GET/status/HTTP/1.0”400 264“-” 10.10.25.3--[19/Jun/2014:13:55:09+0400]“GET/status/HTTP/1.0”400 264“-”

错误日志：

client sent plain HTTP request to HTTPS port while reading client request headers

这是我的Nginx设置！我有什么遗漏吗

worker_processes  1;
error_log  logs/error.log info;
pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

    include   mime.types;
    default_type text/html;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

    gzip  on;
    include /etc/nginx/conf.d/*.conf;

server {
        listen       80;
        listen 443;
        server_name  localhost;
        access_log  logs/host.access.log  main;
        ssl                  on;
        ssl_certificate      /etc/nginx/conf/self-ssl.crt;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers   on;

    }

}

删除上的

ssl，并将
ssl
修饰符添加到
listen443

server {
    listen 80;
    listen 443 ssl;
    server_name  localhost;
    access_log  logs/host.access.log  main;
    ssl_certificate      /etc/nginx/conf/self-ssl.crt;
    ...

仍然是相同的错误有时返回200一些400如何进行健康检查？通过F5 GET/status/return应该是200或301
