@tsullivan @Alex_Piggott @Francisca_Lima and others interested.

Looks like you should use

`proxy_set_header Host $proxy_host;`

instead of

`proxy_set_header Host $host;`

`$proxy_host` takes host value from `proxy_pass` directive, while `$host` will contain your `server_name`. And apparently, Kibana from Elastic Cloud requires an original host to determine target cluster ID.

Works for me without proxifying any additional `X-Found-Cluster` headers.
