Hi, I've upgraded from 1.5 to 2.0 by adding the new repo and performing a yum update. After the upgrade I had to cleanup the plugins folder, then installed head plugin again and elasticsearch started just fine. Local queries seem to work fine and so does Kibana. The problem is when I try to connect via browser to the head plugin (or any other direct query) I get a connection refused. The elasticsearch.yml seems ok, as it states that by default it will listen on the interface 0.0.0.0, which is what I want. Any ideas on what could be happening here? And what can I do to get it to listen in all interfaces again or discard that as the problem? Thanks, Isaac ---

Head plugin has not been updated to 2.0.0 AFAIK. ---

ok, so that's explains why it doesn't work.... Any reason for direct queries through the browser not working? I deleted the folder \_site under plugins because it was making it fail to start, would that have anything to do? ---

May be CORS settings? Or network.host is not set and you are trying to access it from another computer? ---

That's the first think I've checked, the network.host. It's as default, which in theory means it bins to all IP addresses, and it was working before the update. But a netstat shows it only listening on 127.0.0.1. Not sure what other option would I need to change in ES2 to make it listen in all interfaces ---

Found it, ES2 by default binds to _local_ which is 127.0.0.1, I had to change the setting network.bind\_host to 0.0.0.0 and now it works fine. Thanks for pointing me in the right direction 😄 ---
