Hello,

Here is my configuration :

Elasticsearch, Logstash and Kibana are running behind a reverse proxy Nginx.  
ELK are all running in docker containers at the latest stable version (6.4.1) using network host configuration.

The configuration is **working well in IPV4** , but **not in IPV6**. Behind reverse proxy, we explicitly use IPV4 (127.0.0.1) to connect ELK.  
Logstash and Kibana are working well both in IPV4 and IPV6.

 

Kibana Status is OK :  
[![kibana status](https://us1.discourse-cdn.com/elastic/original/3X/e/d/ed70782d756a8ba6572d1abe47c0a07730720f93.jpeg)](https://user-images.githubusercontent.com/30900065/46420930-577dfe80-c731-11e8-80cb-bb801ee1dc0b.jpg)

 

Kibana is able to get all his configuration, visualizations and dashboard from Elastic. I can also use dev tools to launch a custom request to Elastic from Kibana without any problems.

But Kibana Discover, Visualise and Dashboard produce errors like :  
[![discover error](https://us1.discourse-cdn.com/elastic/original/3X/a/6/a6dab1bd5bdf50d9aa79efefc5acfbdad9525fb1.jpeg)](https://user-images.githubusercontent.com/30900065/46420252-e5f18080-c72f-11e8-9b08-6e1a28fe91e1.jpg)

There is no error in any logs (Elastic and Kibana).

We can see this error in browser debug console :
