Can't log when using nginx reverse proxy with gitbucket on tomcat

Hi,

I have installed gitbucket on tomcat8 (with something like that: http://exemple.org:8080/gitbucket) and I use nginx reverse proxy (to access it with http://git.exemple.org)

I can log in with http://exemple.org:8080/gitbucket but not with http://git.exemple.org: when I do that, it seems it simply reload the page.

I try to change the base url in the gitbucket.conf, without sucess.

What can I do?

here is my nginx configuration

server {
    server_name git.exemple.org;

    location / {
        proxy_pass              http://localhost:8080/gitbucket/;
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout   150;
        proxy_send_timeout      100;
        proxy_read_timeout      100;
        proxy_buffers           4 32k;
        client_max_body_size    500m; # Big number is we can post big commits.
        client_body_buffer_size 128k;
    }

     location /assets/ {
        proxy_pass              http://localhost:8080/gitbucket/assets/;
        proxy_cache             cache;
        proxy_cache_key         $host$uri$is_args$args;
        proxy_cache_valid       200 301 302 1d;
        expires                 1d;
    }
}

It seems to be a problem of cookie path. try this configuration.

proxy_cookie_path /gitbucket/ /;
