Nginx 流和上游到 VMware UAG 的问题

Question

我正在尝试使用 Nginx 设置 VMware UAG 负载平衡。我一直收到此错误，

nginx: [emerg] "stream" directive is not allowed here.

我不确定我做错了什么。我绝不是一名开发人员，所以请原谅我的无知。提前致谢 以下是我的配置：

stream {
    upstream vdi_ssl {
        hash $remote_addr;
        server uag-01.example.com:443;
        server uag-02.example.com:443 down;
    }

    upstream vdi_pcoip {
        hash $remote_addr;
        server uag-01.example.com:4172;
        server uag-02.example.com:4172 down;
    }

    server {
        listen 10.4.44.2:443 ssl;

        health_check;
    }

    server {
        listen 10.4.44.2:4172;

        proxy_pass vdi_pcoip;
        proxy_timeout 20m;

        health_check port=443;
    }

    server {
        listen 10.4.44.2:4172 udp;

        proxy_pass vdi_pcoip;
        proxy_timeout 20m;
    }
}
