"This Elastic installation has strict security requirements enabled that your current browser does not meet

Hi All

I am not able to access the Kibana UI .

I am using Google Chrome (ver 87). The error I am getting is

"This Elastic installation has strict security requirements enabled that your current browser does not meet."
I have tried other browsers (Edge, firefox etc) without any success.

This is a new installation 0f version 7.10

# rpm -qa|grep -i -E "elastic|kibana|logstash|fileb"

I have confirmed Elasticsearch is running

# netstat -tulpn|grep -e java -e node

Can any one help ?

Kibana shows this message when a browser doesn't satisfy the CSP requirements (namely, it doesn't specify unsafe-inline) in strict mode (csp.strict: true). There seems to be a problem with configured csp.rules.

Can you suggest what should be the rules please ?

This is what I have now

 - "script-src https://MYSERVER.example.com 'self' 'unsafe-inline' 'unsafe-eval' https://*"
 - "child-src 'MYSERVER'"
