174	Problem with redirection when subdomain string is the same as the upstream name	Jean-Marc Dormoy	somebody	"Hi,
I have now the following configuration: 
in nginx.conf

   upstream blogupstream{
        server 10.10.0.220:80;
    }

in conf.d/blog.conf
server {
	listen 		80;
	server_name 	blog.XXX.com;
	location / {
                proxy_set_header Host $host;
                proxy_set_header X-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-Proto $server_protocol;

		proxy_pass	http://blogupstream;
	}
}
[ got also a ssl section]

This configuration is now working fine BUT, I use to have the following 
   in nginx.conf :        upstream blog
   in blog.conf :          proxy_pass http://blog

the blog is running with Wordpress, and with this initial set up, there was some strange redirections on subdirectories like:

https://blog.XXX.com/wp-admin/post.php?post=439&action=edit   

redirected to :

https://blog.XXX.com/wp-admin/.XXX.com/wp-admin/post.php?post=439&action=edit 

I initially thought it was a problem with wordpress, but it turned to work correctly when I changed the upstream string from ""blog"" to ""blogupstream""

Don't know if this is a bug or a  known issue (shame on me if I didn't read correctly all the documentation).

Best
