nginx proxy blocking file upload viewing

Added by Mitch Pirtle over 12 years ago

In a nutshell I can fire up redmine using mongrel and surf to :3000 and everything works. If I then proxy to :3000 from nginx, everything works except viewing file uploads (for wiki entries, tracker items, whatever).

Looks like the image requests are getting mangled somewhere in nginx, or in the host config. Ultimately the URL for an uploaded file looks like this:

Going to the one hosted on works fine, going through (nginx) results in a 404.

Please let me know what I can do to figure this out, has been annoying the ** out of me for far too long! :-)

This is a debian machine running 64 bits, running nginx 1.0.10:

Here's my relevant bits from

upstream mongrel_cluster {

server {

   access_log  /var/log/nginx/;
   error_log   /var/log/nginx/;

   include proxy.include;
   root /var/www/;

   location ~* \.(js|css|jpg|jpeg|gif|png)$ {

   location / {
       try_files $uri/index.html $uri.html $uri @fallback;

   location @fallback {
       proxy_pass              http://mongrel_cluster;

Anybody here have this issue, and did you figure it out?

5 years late but maybe someone else has the same issue
-> it's the image cache of nginx
