All,

I am not able to open Elastic Kibana Dashboard on my browser. The browser states "Something went wrong" and to try to refresh the page. Refreshing the page does not do anything.

I get the following error: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "default-src 'self' http: https: data: blob: 'unsafe-inline'".

Can you all please help with this issue?

Hi  
Which Browser are you using? Is it just happening when you open Dashboards or also when you open Discover?  
Best,  
Matthias
