Proxy setup for kibana using nginx

Elastic Stack Kibana
1

I am trying to setup a proxy for Kibana. All required services are running for me.
I have the following configuration file under /etc/nginx/sites-available

server {
    listen 80;

    server_name testkibana;

   auth_basic "Restricted Access";
    auth_basic_user_file /etc/nginx/htpasswd.users;

    location / {
        proxy_pass http://localhost:5601;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

I have already tried removing authorisation as below :

server {
    listen 80;

    server_name testkibana;

   auth_basic "off";

    location / {
        proxy_pass http://localhost:5601;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

I am trying to access kibana through testkibana, but I get below page

What am I doing wrong here ?

This looks like a Nginx issue, not a Kibana issue, you will probably find a solution looking for similar Nginx issues on StackOverflow for example.

Are Nginx and Kibana on the same server? What does your kibana.yml looks like?

But, why use Nginx in front of Kibana to have authentication?

Thanks for you response. It certainly looks like a nginx issue. I have tried some answers found on stackoverflow, but none seem to work.

That is why I have removed authentication using auth_basic "off";

Below is my Kibana.yml :

1 # Kibana is served by a back end server. This setting specifies the port to use.
  2 server.port: 5601
  3 
  4 # Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
  5 # The default is 'localhost', which usually means remote machines will not be able to connect.
  6 # To allow connections from remote users, set this parameter to a non-loopback address.
  7 server.host: "localhost"
  8 
  9 # Enables you to specify a path to mount Kibana at if you are running behind a proxy.
 10 # Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath
 11 # from requests it receives, and to prevent a deprecation warning at startup.
 12 # This setting cannot end in a slash.
 13 #server.basePath: ""
 14 
 15 # Specifies whether Kibana should rewrite requests that are prefixed with
 16 # `server.basePath` or require that they are rewritten by your reverse proxy.
 17 # This setting was effectively always `false` before Kibana 6.3 and will
 18 # default to `true` starting in Kibana 7.0.
 19 #server.rewriteBasePath: false
 20 
 21 # Specifies the public URL at which Kibana is available for end users. If
 22 # `server.basePath` is configured this URL should end with the same basePath.
 23 #server.publicBaseUrl: ""
 24 
 25 # The maximum payload size in bytes for incoming server requests.
 26 #server.maxPayload: 1048576
 27 
 28 # The Kibana server's name.  This is used for display purposes.
 29 #server.name: "your-hostname"

 37 
 38 # The default application to load.
 39 #kibana.defaultAppId: "home"
 40 
 41 # If your Elasticsearch is protected with basic authentication, these settings provide
 42 # the username and password that the Kibana server uses to perform maintenance on the Kibana
 43 # index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
 44 # is proxied through the Kibana server.
 45 #elasticsearch.username: "kibana_system"
 46 #elasticsearch.password: "pass"
 47 
 48 # Kibana can also authenticate to Elasticsearch via "service account tokens".
 49 # If may use this token instead of a username/password.
 50 # elasticsearch.serviceAccountToken: "my_token"
