Description:

I configured an nginx reverse proxy to make my sites available through a domain. The domain is secured with basic authentiction. For 3 upstream servers all is well, but for my domoticz upstream server I get stuck.

Looking in the access log I can see that all the communication is going ok up until the point that we reach the statement below. After that all responses get a 401 Unauthorized (from the accesslog nginx):

192.168.2.254 - [email protected] [02/Feb/2024:14:51:14 +0100] "GET /domoticz/json.htm?type=command&param=getdevices&filter=all&used=true&favorite=1&order=[Order]&plan=0 HTTP/1.1" 401 91 "https://hildering.ddns.net/domoticz/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36"

This results in the domoticz screen 'communication lost'.

I suspect some script is causing this. Running https://hildering.ddns.net/domoticz/jso ... getversion the output is correct and the accesslog show a 200:

192.168.2.254 - [email protected] [02/Feb/2024:15:15:56 +0100] "GET /domoticz/json.htm?type=command&param=getversion HTTP/1.1" 200 46 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36"

Anyone to help me with this problem? Willing to supply all necessary data.

Did you use this page to setup your nginx? https://www.domoticz.com/wiki/WebServer_Proxy

A friend of mine also pointed me in that direction. I'll have a look...

bad luck, did not work, same errors. From the web_server doc:

for example: https://www.mydomain.com/domoticz/ ===> http://192.168.0.210:8080

This is exactly what I do... I have copied the nginx settings into the location part. No luck (even after creating and setting the $connection_upgrade variable)
this looks familiar:

Code: Select all

  location /domoticz {
    rewrite ^/domoticz/?(.*) /$1 break;
    proxy_http_version 1.1;
    proxy_read_timeout 90;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Scheme $scheme;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Connection $connection_upgrade;
    add_header X-Frame-Options SAMEORIGIN;
    proxy_set_header  Authorization $http_authorization;
    proxy_pass http://192.168.0.210:8080/;
  }

my setting in domoticz:

• one username/password; same as basic authentication

• Allow Basic-Auth authentication over plain HTTP (API only) = ON

• trusted networks: 127.0.0.*; 192.168.*.*; localhost

I really have no clue...

If it can't be done the way it should be done, then it should be done the way it can be done...

So I have chosen not to use the authentication of NGINX reverse proxy for security for domoticz, but the authentication that domoticz itself offers.
It means that in NGINX the authentication is enabled for all upstream servers, except for domoticz. In domoticz I have limited the trusted domains to only my local network. So, if you connect to domoticz via the public address, you must therefore always log in. And that was one of the non-functional requirements!
NGINX becomes very symple...

Code: Select all

  
  location /domoticz/ {
    auth_basic off;
    proxy_pass http://192.168.0.201:8080/;
  }

In domoticz:

• API protection = OFF

• just ONE trusted domain

All servers run like clockwork (as it should be)
