Kibana port not work property

[weyderfs (Weyder Ferreira)]

Dear,
Is anyone else having trouble accessing Kibana in the browser either via port 5601 or via 80 with authentication via NGINX?

My scenery:
O.S: Ubuntu Server Minimal 18.04 - LTS
Firewall: UFW disable
I made the entire installation via repository, following some tests:

mservice@sentinel:~$ sudo ufw status
[sudo] password for mservice:
Status: inactive
mservice@sentinel:~$ curl -v http://127.0.0.1:5601
* Rebuilt URL to: http://127.0.0.1:5601/
*   Trying 127.0.0.1...
* TCP_NODELAY set
* connect to 127.0.0.1 port 5601 failed: Connection refused
* Failed to connect to 127.0.0.1 port 5601: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 127.0.0.1 port 5601: Connection refused

When access via browser return error 501 - bad gateway

What does your NGinx proxy look like?

@tylersmalley, I wrote it:

server {
        listen 80;

        server_name sentinela;

        auth_basic "Acesso Restrito!";
        auth_basic_user_file /etc/nginx/htpasswd.kibana;

        location / {
            proxy_pass http://192.168.10.128:5601;
            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'm not familiarity with NGinx.
