I have installed elasticsearch and kibana ( version 5.0.1 for both) on the same server.
Rather than using the default values for network.host, elasticsearch.url and server.host, I am using the DNS entry for the server.
Kibana and Elasticsearch work fine for a number of hours, albeit they are a little slow, until suddenly it stops working. I get the error that the request timeouts after 3000ms when I run a search in Discover.
Then Kibana stops me from carrying out any searches or visualisations and I get the following error page.
If that image doesn't work - the main errors are :
- Status: Red
- UI settings : Elasticsearch plugin red
- plugin:firstname.lastname@example.org : Request timeout after 3000ms.
If anybody know why this error suddenly appears, I'd be very grateful to hear.
At the moment I just uninstall elasticsearch and then reinstall it and it works, but this is not a practical solution.
