Unable to fetch mapping

i have upgrade kibana 3 to kibana 4 and when go to dashboard, ask me an index patterno but i have the error:

Unable to fetch mapping. Do you have indices matching the pattern?

The indices existing, kibana 3 working perfectly, if i get curl http://127.0.0.1:9200/_cat/indices i view the indices:

Is configured with proxypass and nginx (if it could be useful)

Answer 1

I resolved disabling the other directives to ngnix:

#  location ~ ^/_aliases$ {
#    proxy_pass http://127.0.0.1:9200;
#    proxy_read_timeout 90;
#  }
#  location ~ ^/.*/_aliases$ {
#    proxy_pass http://127.0.0.1:9200;
#    proxy_read_timeout 90;
#  }
#  location ~ ^/_nodes$ {
#    proxy_pass http://127.0.0.1:9200;
#    proxy_read_timeout 90;
#  }
#  location ~ ^/.*/_search$ {
#    proxy_pass http://127.0.0.1:9200;
#    proxy_read_timeout 90;
#  }
#  location ~ ^/.*/_mapping {
#    proxy_pass http://127.0.0.1:9200;
#    proxy_read_timeout 90;
#  }
#  location ~ ^/.*/_cluster$ {
#    proxy_pass http://127.0.0.1:9200;
#    proxy_read_timeout 90;
#  }
...

I have upgrade from kibana 3 and it's the old configuration of ngnix, i have commented all location
