here I've putted all the configs I cut find, but I still getting an 504 timeout error on uploading a file about 20 megabytes, its less than 2 minutes, can you look at these settings and tell me what I'am missing?, I've restarted the server after putting all this, but didn't helped, please help! Ican't upload files

You need to configure fastcgi_read_timeout in your location scopes.

location {
     ... 
     fastcgi_read_timeout 900s; # 15 minutes
     ...
}

Also what you can do to clean up your config (this is optional) is you can putt all the proxy_set_headers along with timeout in eg /etc/nginx/fastcgi_settings :

proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
fastcgi_read_timeout 900s;

Then you can remove all the proxy_set_header so you do not have to repeat them, and put this instead of them:

include /etc/nginx/fastcgi_settings

That will make your config easier to maintain.

Old Answer These variables must be defined in server scope, not in http scope. Also, if you are proxying to php, you also need to set

proxy_read_timeout 120;
proxy_connect_timeout 120;

If you are still having problems, please provide full configuration.
