503 Error: service unavailable

Elastic Stack Kibana
2

Hi there chaixl,

A few questions to help me better understand what may be happening in your situation:

  • Are you running Kibana behind a proxy? If so, are there any error logs in the proxy's logs?
  • Are other functions working correctly? Can you view dashboards or visualizations? If so, it is only failing when you try to save things?
  • What is the response of hitting the /_status endpoint in Elasticsearch? It's possible you have a shard-related issue in the cluster.

(I have saved almost 165 objects in the kibana,Is it possible that there are too many saved objects.)

This should not be a problem unless you have an Elasticsearch cluster that does not have enough disk space or available RAM. We support Kibana deployments with 1000s of objects.
