Setup behind nginx

Hi,
With v1 it works right out the box. My nginx config is as follows:

upstream mattermost_proxy {
  server 192.168.10.10:8065;
}

server {
  listen       443;
  server_name  chat.example.com;

  ssl on;
  ssl_certificate      /etc/nginx/ssl/server.crt;
  ssl_certificate_key  /etc/nginx/ssl/commercial.key;

  ssl_session_cache shared:SSL:1m;
  ssl_session_timeout  5m;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

  location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://mattermost_proxy;
  }

  location /api/v1/websocket {
    proxy_pass http://mattermost_proxy;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
  }

  client_max_body_size 4G;
  keepalive_timeout 10;
}

Websocket requires the special config as documented here: https://www.nginx.com/blog/websocket-nginx/
