I have an ELK cluster running and I have trouble loading Kibana in my web browser. It was working fine until 3 days before I made a change to logstash configuration. I installed Logstash-amazon_es plugin, used to load data to Amazon Elasticsearch cluster. All the services are up and running fine without errors. I have checked the logs and could not find any errors. I have traced back my steps and uninstalled all the changes made, but yet I am not able to resolve this Kibana errors.
About the ELK stack configuration:
- A cluster of 4 nodes
- Kibana is running behind a Nginx reverse proxy
- The entire cluster is accessible inside a VPN and have an another Nginx proxy running
- Kibana version - 6.8.13
- Logstash version - 6.8.13
- Elasticsearch version - 6.8.13
Errors I see in browser
Any help troubleshooting this is much appreciated!
