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"
30
31 # The URLs of the Elasticsearch instances to use for all your queries.
32 elasticsearch.hosts: ["http://localhost:9200"]
33
34 # Kibana uses an index in Elasticsearch to store saved searches, visualizations and
35 # dashboards. Kibana creates a new index if the index doesn't already exist.
36 #kibana.index: ".kibana"
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"
51
52 # Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
53 # These settings enable SSL for outgoing requests from the Kibana server to the browser.

55 #server.ssl.certificate: /path/to/your/server.crt
56 #server.ssl.key: /path/to/your/server.key
57
58 # Optional settings that provide the paths to the PEM-format SSL certificate and key files.
59 # These files are used to verify the identity of Kibana to Elasticsearch and are required when
60 # xpack.security.http.ssl.client_authentication in Elasticsearch is set to required.
61 #elasticsearch.ssl.certificate: /path/to/your/client.crt
62 #elasticsearch.ssl.key: /path/to/your/client.key
63
64 # Optional setting that enables you to specify a path to the PEM file for the certificate
65 # authority for your Elasticsearch instance.
66 #elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]
67
68 # To disregard the validity of SSL certificates, change this setting's value to 'none'.
