I'm a noob working with Nginx.
My nginx is setup on docker - i can't seem to find how the " ssl_certificate" and "ssl_certificate_key" paths.
Can someone direct me towards where these values can be found and where above conf need to be added?

If you're using SWAG or a similar docker (nginx with auto letsencrypt/certbot), there's a chance you don't need to explicitly set ssl certs and/or ssl, just include the ssl.conf in this config.
Something like:
include /config/nginx/ssl.conf

Please take this with a huge grain of salt (a mountain of it) as I'm a total noob who's just looking around at how to proxy non http(s) traffic to unifi controler so as to adopt a USG remotely and proxy all the ports/traffic through nginx as securely as possible. I HAVE MOSTLY NO CLUE WHAT I'M TALKING ABOUT!

and then you need to e.g. bind-mount the certs/keys files from your host to your docker container.
Lets assume, they live on /host-path/to/cert.pem and /host-path/to/key.pem. If you use docker-compose, an except of the config might look like this

    volumes:
      - '/host-path/to/cert.pem:/container-path/to/cert.pem:ro'
      - '/host-path/to/key.pem:/container-path/to/key.pem:ro'

Thanks for the reply. I'll give this a try.

I took the original and added this line to the location /wss/ section and it seems to work.
proxy_set_header Origin '';

This also worked for me. The errors in the user interface disappeared. The return code in Nginx changed from 404 to 101 (Switching protocol).

This solved it also for me :) Thx!

Hi, I found myself wanting to do this for putting the Unifi controller inside an iFrame to use with HomeAssistant.

To add it into the iFrame you need to set a few additional headers into both the location /wss/ and location / parts of the nginx conf.

Here they are:

# Headers required for unifi to work
proxy_hide_header X-Frame-Options;
proxy_hide_header X-XSS-Protection;
proxy_hide_header X-Content-Type-Options;
proxy_cookie_path / "/; secure; SameSite=none";
add_header X-Frame-Options "ALLOWALL";
