Kibana "No living Connections" behind IPV6 reverse proxy

[Kirack2040]

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 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 :

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

We can see this error in browser debug console :
