Nginx as reverse proxy?

    I am having some issues configuring nginx as a reverse ssl proxy for Guacamole. I assume some of you have been able to set this up succesfully? Am I missing something?

    Hereby the config so far:

    Tomcat (under connector)


    Nginx (location stuff)

    location / {
    proxy_pass http://localhost:8080/guacamole/;
    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
    proxy_redirect off;
    proxy_buffering off;
    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_set_header X-Forwarded-Proto https;
    proxy_pass_header Set-Cookie;
    proxy_pass_header P3P;

    I've got this NGINX setup in my sites-enabled for usage with Tomcat7 and Guacamole 0.9.4:

    # SERVER LISTENING ON PORT 80 to redirect to HTTPS per default
    server {
        listen 80;
        location / {
                rewrite ^/(.*)$1 permanent;
    # ANOTHER SERVER LISTENING ON PORT 443 (SSL) to secure the Guacamole traffic and proxy the requests to Tomcat7
    server {
        listen 443 ssl;
    # This part is for SSL config only
        ssl on;
        ssl_certificate      /etc/nginx/ssl/your-external-servername.pem;

        proxy_buffering off;

        proxy_cookie_path /guacamole/ /;
        location / {
                # I am running the Tomcat7 and Guacamole on the local server
                proxy_pass http://localhost:8080;
