Kibana/nginx configuration - Problem after upgrade

After the last upgrade when I access Kibana I am redirect in app/kibana instead the root.

Ex. x.x.x.x:5601/app/kibana

I tried different configuration settings without results.
Do you have any idea how to deal with this problem?

Thanks in advance.

its a design change in the new kibana. See https://github.com/elastic/kibana/issues/5230 . I think you'll find what you need to reconfigure nginx to deal with your issue.

Thanks but those settings did not help me.

I still get the following error:

[error] 31713#0: *3 connect() failed (111: Connection refused) while connecting to upstream, client: 10.16.0.80, server: _, request: "GET /bundles/commons.style.css?v=9693 HTTP/1.1", upstream: "http://[::1]:5601/bundles/commons.style.css?v=9693", host: "10.16.0.76", referrer: "http://10.16.0.76/app/kibana"
