Kibana did not load properly

After some upgrades it could happen as to new locations are available in Kibana that need to be accessed. For example like the issue here - https://github.com/StamusNetworks/SELKS/issues/238

To begin with make sure your nginx config is always up to date as the one here:

root@SELKS:~# cat  /etc/nginx/sites-available/selks6.conf
server {
    listen 127.0.0.1:80;
    listen 443 default_server ssl;
    ssl_certificate /etc/nginx/ssl/scirius.crt;
    ssl_certificate_key /etc/nginx/ssl/scirius.key;
    server_name SELKS;
    access_log /var/log/nginx/scirius.access.log;
    error_log /var/log/nginx/scirius.error.log;

    # https://docs.djangoproject.com/en/dev/howto/static-files/#serving-static-files-in-production
    location /static/ { # STATIC_URL
        alias /var/lib/scirius/static/; # STATIC_ROOT
        expires 30d;
    }

    location /media/ { # MEDIA_URL
        alias /var/lib/scirius/static/; # MEDIA_ROOT
        expires 30d;
    }

    location /app/moloch/ {
        proxy_pass https://127.0.0.1:8005;
        proxy_redirect off;
    }

    location /plugins/ {
        proxy_pass http://127.0.0.1:5601/plugins/;
        proxy_redirect off;
    }

    location /dlls/ {
        proxy_pass http://127.0.0.1:5601/dlls/;
        proxy_redirect off;
    }

    location /socket.io/ {
        proxy_pass http://127.0.0.1:5601/socket.io/;
        proxy_redirect off;
    }

    location /dataset/ {
        proxy_pass http://127.0.0.1:5601/dataset/;
        proxy_redirect off;
    }

    location /translations/ {
        proxy_pass http://127.0.0.1:5601/translations/;
        proxy_redirect off;
    }

    location ^~ /built_assets/ {
        proxy_pass http://127.0.0.1:5601/built_assets/;
        proxy_redirect off;
    }

    location /ui/ {
        proxy_pass http://127.0.0.1:5601/ui/;
        proxy_redirect off;
    }

   location /spaces/ {
        proxy_pass http://127.0.0.1:5601/spaces/;
        proxy_redirect off;
    }

  location /node_modules/ {
        proxy_pass http://127.0.0.1:5601/node_modules/;
        proxy_redirect off;
    }

  location /bootstrap.js {
        proxy_pass http://127.0.0.1:5601/bootstrap.js;
        proxy_redirect off;
    }

 location /internal/ {
        proxy_pass http://127.0.0.1:5601/internal/;
        proxy_redirect off;
    }

 location ~ "^/([\d]{5}/.*)" {
        proxy_pass http://127.0.0.1:5601/$1;
        proxy_redirect off;
    }


 location / {
       proxy_pass http://127.0.0.1:8000;
       proxy_read_timeout 600;
       proxy_set_header Host $http_host;
       proxy_set_header X-Forwarded-Proto https;
        proxy_redirect off;
    }

}

Then restart nginx :

systemctl restart nginx
