License Issue

Elastic Stack Elasticsearch
1

i have a basic license and it is correct and working. Once i loaded it with curl XPUT it worked as expected.
But later that day i got this:

[warning][license] license information could not be obtained from elasticsearch 
Error: Request timeout after 3000ms

Why?

That's not a problem with your license, it's a problem with the server communicating with Elasticsearch. Basically, it made a request to check your license, and didn't get a response within 3 seconds.

Was Elasticsearch under heavy load, or in the process of being restarted?

Did it work at all before you saw that message? If not, it could be a configuration issue somewhere that is preventing communication with Elasticsearch.
