Viewing very old imported logs with Kibana fails

Hello. My elasticsearch/kibana3 install is few month old and I have imported some logs from 2012 and 2014 and Kibana just fails when I enter year 2012.
When I try to go back in time it sohws me the 2014 data that has been there for some time now and at some point when I enter 2013 it tells me there is no idices from that time but when I try to look at the events from 2012 (that I just imported) it fails with Connection Failed.

Should I wait so Elasticsearch is maybe creating the inexes as I just imported the data?

okei... after some time it worked.
