Hello,

I have ELK stack installed with:  
Elasticsearch version 7.11  
and  
Kibana 7.8.1 with RoR free version for security.  
I plan also to upgrade Kibana to a version more appropriate to elastic search 7.11.

I have the following issues:

When trying to create new index patterns I have the following errors:  
Failed to load indices  
and  
Failed to load remote clusters

Error that I observe on Browser Console:  
Failed to load resource: the server responded with a status of 500 (Internal Server Error)

1. displayName: "InternalServerError"
2. message: "Internal Server Error"
3. path: "/_%3A_/\_search"

Could you please help me find the issue?

Hello @FOMihai

I'm confused about which version of Elasticsearch and Kibana you're running as they need to be on the same version.

Could you post a screen capture of the action that creates the error and a har file to capture it?

Thanks,  
Matt

Hello,  
I plan then to downgrade the Elasticsearch version.

I can see by the har file that the search requests responses don't have a result body.

First we should make sure kibana is properly communicating with Elasticsearch. Check back once they're both running the same version.

Thanks,
