Ever tried to run proxmox behind NGINX Reverse Proxy to get nice urls with HTTPS? Ever since some version of 7.x was released several errors may appear resulting in the gui unable to load using reverse proxy.

Chances are that you have a badly configured or missing proxy_buffering setting in your nignx config file. Ensure proxy_buffering are set to "off", having proxy buffering disabled in nginx ensures all responses is sent synchronously. If the below configuration doesn't solve the issue ensure that no buffering headers are set, e.g. X-Accel-Buffering, which may be disabled using the proxy_ignore_headers setting.
