Index / Visualization Mismatch about rock HOT 3 OPEN

This could be an issue with Elastic 7.11 it looks like. I will keep this open but want to try another elastic version to see if we get the same errors with the dashboards before changing them.

As discussed I believe a good place to look for this issue is in the lighttpd proxy config. I confirmed this in 7.11 but didn't test 7.12. Here is a snippet of the lighttpd error log:

2021-03-11 16:10:38: (http-header-glue.c.1032) proxy backend sent invalid response header (Transfer-Encoding) to HTTP/1.0 request
2021-03-11 16:10:38: (gw_backend.c.2125) response not received, request sent: 927 on socket: tcp:127.0.0.1:5601 for /internal?, closing connection

from rock.

Ended up removing the lighttpd which was buggy and installed nginx.

You can use this simple configuration as it works, but if your rock web access is in a closed network only.
If you feel like switching to a SSL certificate and auth you will have a little bit more work to do.

        location / {
                proxy_pass http://127.0.0.1:5601;
                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;
                proxy_set_header    Host            $host;
                proxy_set_header    X-Real-IP       $remote_addr;
                proxy_set_header    X-Forwarded-for $remote_addr;
                port_in_redirect off;
                proxy_connect_timeout 3600;
            }

Also in kibana.yml add this so it doesn't buzz all the time with the publicbaseurl notice:

server.publicBaseUrl: "http://127.0.0.1:5601"
server.host: 127.0.0.1
server.port: 5601

Hope it helps.
