This worked for me with one tweak. I am using a stand-alone nginx server for multiple sites. I ended up changing the proxy_pass lines to direct them to my actual internal IP Address.
The rest of this setup worked amazingly.
THANK YOU!!!
works a fuckin' treat. thx a ton.
This does not work for inform-urls.
Mine was working without the wss
part, I'll see with time if it improves or not.
Nevertheless, I still get HTTP 413 when uploading large backups (>1Mb). It seems to be nginx, as there are no errors on the unifi part. Adding this does the trick: client_max_body_size 10M;
The https is very important the proxy_pass https://localhost:8443/
line. I was copy/pasting from an old config and kept getting
the error: This combination of host and port requires TLS.
I had forgotten to change the http -> https.
After a bunch of trial and error the configuration below is finally how I got the web socket errors to stop. Its a hybrid of my own, @vidia and @tongphe I have the server block repeated twice on different ports for my guest portal which I'm also proxying through nginx.

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

The above is perfectly fine.
Hi guys,
may i know if this code works for AP adoption "inform"?
Hi guys,
may i know if this code works for AP adoption "inform"?
what is everyone doing about the STUN warning, have you been able to solve this?
Thank you to everyone who has responded to this. I will have to go through all of these suggestions and take in whatever new changes are working best for people. I have the posted code deployed currently and haven't noticed any issues, but it is possible I've missed something because I haven't updated it since I posted it initially.
@azN2, I do have STUN issues on my box, but my issues seem to be because STUN is binding to ipv6 and not ipv4, which is causing it to not be accessible over ip4 like I want it to be. I haven't found a solution to force it to use ipv4, but I'm mentioning it here in case that bit of info helps you find your own solution.
@rexkani, I believe this will work for /inform. I don't believe that will be anything special or different than accessing the controller regularly.
hi @azN2 and @vidia, the code did not work for STUN and inform, these traffics does not run on HTTPS and therefore needs to make use of the nginx "Stream" module. i've leart that from below discussion:
another thing that is still missing after adding the stream for STUN and inform is the remote guest captive portal. i seems to be running on 8880? i dont have time to work on it yet.
Thank you. You directed me into the right direction. Here is "my snippet", which basically enables websockets & httpupgrade on / (catchall) instead of splitting between / and /wss. The reason is, that more locations than just /wss need http upgrade
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name MY.DOMAIN;
#SSL/TLS config
include /PATH/TO/SSL.CONF;
location / {
#Unifi ip
proxy_pass https://10.1.0.106:8443/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_ssl_verify off; # Ignores the unifi controller's self-signed certificate (potentially allows MITM - Add the certificates, as shown for the other examples above, in order to mitigate this attack vector)
#"Upgrade" for WebSockets
proxy_http_version 1.1;
proxy_buffering off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_read_timeout 86400;
}
}
As a little sidenote: If you plan to use HTTP Auth, you need to block forwarding of the auth-data to the unify-controller. Otherwise you will end up with a 400: Bad Request error.
Simply add this line to the location block
proxy_set_header Authorization "";
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).
The https is very important the
proxy_pass https://localhost:8443/
line. I was copy/pasting from an old config and kept getting
the error:This combination of host and port requires TLS.
I had forgotten to change the http -> https.
This was my issue as well. This fixed it for me!
I realize this is for self hosted controller, however, can anyone let me know if you've been able to get nginx reverse proxy working with a Cloud Key Gen 2 Plus? I am able to get to a login screen, but when UniFi attempts to perform the two factor auth, it bombs out. Any help would be appreciated.
Does anyone have a good example of doing this but with a location like /unify/? I can run it from root fine but once I change the location. I cant get it to work :(

i believe it is possible to do, but i don't think it's a good idea unless they add a setting in the controller to support that. otherwise it's too much of a kludge. upvote this maybe? https://community.ui.com/questions/Request-Add-a-controller-config-option-for-http-path-prefix/416eb730-d01d-4de5-b336-381091e01c0c

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?

This is more an nginx and docker related question.
However, you still need basically the nginx-config for having ssl to be enabled
ssl on;
ssl_certificate /container-path/to/cert.pem;
ssl_certificate_key /container-path/to/key.pem;
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'
The ro tag is there to make the files read-only in the container.
Adjust for your usecase (bare-docker, k8, rancher, portainer etc accordingly).

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!

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

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

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";
hi to all, i configure them, but open a white paga without any error.
location /wss/ {
proxy_pass https://192.168.1.5:8443;
proxy_http_version 1.1;
proxy_buffering off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_read_timeout 86400;
}
location / {
proxy_pass https://192.168.1.5:8443;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_http_version 1.1;
proxy_set_header Connection "upgrade";
}
thank you thank you thank you!!!!
