Getaddrinfo EAI_AGAIN elasticsearch

[cyberzlo]

I have following problem with Kibana, which just installed with whole ELK stack on fresh system Ubuntu 20.04.4 LTS:
Kibana server is not ready yet.
Error in logs:

{"ecs":{"version":"8.0.0"},"@timestamp":"2022-05-15T15:32:25.451+00:00","message":"Unable to retrieve version information from Elasticsearch nodes. getaddrinfo EAI_AGAIN elasticsearch","log":{"level":"ERROR","logger":"elasticsearch-service"},"process":{"pid":3897},"trace":{"id":"b2add3a6bb3f0429649b82219b489cad"},"transaction":{"id":"b53caeed1f19bf23"}}

Packages version:

Hi,

Please check this post, and if possible share the Kibana yaml file.

Kibana cannot connect to ES cluster - Unable to retrieve version information from Elasticsearch nodes

It was my mistake. I set ELASTICSEARCH_URL but Elasticsearch use variable ELASTICSEARCH_HOSTS. I would expect that Kibana will log something more than just Unable to retrieve version information from Elasticsearch nodes..
