问题：

修改nginx 配置文件：

 location ~ /cmdb/api {
                proxy_pass http://cmdb2_backends;
                #proxy_set_header            Host $host;

修改之后：

如果不适用upstream,修改proxy_pass 为一个具体的地址：比如 http://ip:port 就可以正常使用。

Invalid HTTP_HOST header: 'localhost:90,localhost:90'. The domain name provided is not valid according to RFC 1034/1035

I am trying to configure nginx along with Gunicorn for a Django project. nginx is giving me the following error:

DisallowedHost at /
Invalid HTTP_HOST header: 'localhost:90,localhost:90'. The domain name provided is not valid according to RFC 1034/1035.

Django ERROR (EXTERNAL IP): Invalid HTTP_HOST header: '*.domain.com'
