python - Issues with nginx reverse proxy to an app server running nginx+django -

i have app running on server a. have server b want use reverse proxy accessing app on server a. server running nginx 1.4.5 , django (python 2.7.6 fastcgi), server b running nginx 1.4.5 well. want add on ssl way.

the proxy kinda working. issue requests don't see passed along correctly. when going https://servera.org/ 404 error instead of log-in page i'm expecting.

this error message seeing in browser (it's error message, know request reaching server a):

page not found (404) request method: request url:    http://nova.iguw.tuwien.ac.at/index.html using urlconf defined in tubadges.urls, django tried these url patterns, in order: 1. ^admin/doc/ 2. ^admin/ 3. ^$ 4. ^badges/?$ 5. ^badges/(?p<uid>\d+)/?$ 6. ^presets/$ 7. ^svg$ 8. ^bgsvg$ 9. 

this config reverse proxy:

upstream server_a {     server servera.org:8080 fail_timeout=0; }  server {     listen              443 ssl;     listen          80;     server_name         subdomain1.serverb.org;     server_name     subdomain2.serverb.org;     keepalive_timeout   70;      ssl_certificate     /etc/certificates/server_b.pem;     ssl_certificate_key /etc/certificates/server_b.key;       error_log           /var/log/nginx/aurora.ssl.error.log error;     access_log          off;      client_max_body_size 50m;      location ~ ^/(.+)$ {         proxy_intercept_errors  off;         proxy_buffering     off;          proxy_connect_timeout 5;         proxy_send_timeout    5;         proxy_read_timeout    5;          proxy_set_header    host                $host;         proxy_set_header    x-forwarded-by      $server_addr:$server_port;         proxy_set_header    x-forwarded-fo      $remote_addr;         proxy_set_header    x-forwarded-proto   $scheme;         proxy_set_header    x-forwarded-for     $proxy_add_x_forwarded_for;          access_log          off;         error_log           /var/log/nginx/tubadges.error.log debug;          proxy_pass          http://server_a;         proxy_redirect      off;     } } 

and config i'm using on server run app:

server {     listen                  8080; ## listen ipv4     server_name             localhost;     server_name             servera.org;     client_max_body_size    5m;     error_log               /var/log/nginx/app1.error.log;     access_log              /var/log/nginx/app1.access.log;      location /static {         root /srv/django/projects/app1;     }     location /media {         root /srv/django/projects/app1;     }     location / {         # host , port fastcgi server         fastcgi_pass unix:/srv/django/run/app1.socket;          fastcgi_param path_info $fastcgi_script_name;         fastcgi_param request_method $request_method;         fastcgi_param query_string $query_string;         fastcgi_param content_type $content_type;         fastcgi_param content_length $content_length;         fastcgi_param server_addr $server_addr;         fastcgi_param server_port $server_port;         fastcgi_param server_name $server_name;         fastcgi_param server_protocol $server_protocol;         fastcgi_param remote_addr $remote_addr;         fastcgi_pass_header authorization;         fastcgi_intercept_errors off;     } } 

i'm assuming it's got django app config or config on server a.

can spot error? need more information?
there, maybe, answer on here have missed?

thanks in advance!

p.s.: first time asking question on stackoverflow, if there's way can improve question better answers, , see bugs, please don't hesitate point out me how can improve question. :)

actually, looks nginx correctly passing request through - error page comes django (so request being serviced apache) , states url:

http://nova.iguw.tuwien.ac.at/index.html

cannot resolved of urls defined in tubadges.urls

you need hit url such http://nova.iguw.tuwien.ac.at/admin/login or that.
