Kibana verion: 7.9.3

I am getting Internal server 500 error - [illegal_argument_exception] application privileges must refer to at least one resource"} on accessing Kibana after I enter the elastic user name and password. Same goes for every user.

I have verified that the .kibana index is getting created when I delete it manually and restart the Kibana

Adding some stack trace from Kibana's logs

Welcome, @rishabhcldcvr!

I noticed it looks like you are running ES v7.9.0 and Kibana v7.9.3, is that intentional? Are you attempting to upgrade to 7.9.3?

Hey @alisongoryachev
Thanks for the reply.

I have re-installed Kibana when this issue occured and after that it has been showing this kibana version mismatch. I have installed it using apt and there I specified the version for kibana=7.9.0. Event the apt list return kibana 7.9.0.

This is the main error I am getting on opening Kibana console from browser.

It looks like there is a problem with your TLS.
What documentation did you follow to setup Security?
Can you show your Elasticsearch and Kibana config?

Hi @warkolm
This was setup one year back and it was running but someone has made changes which no one was aware of what changes were done.
I have installed 7.14.0 version of ES and Kibana after facing issue for such long and it is working now using the same configuration files.
