CSP with Nginx proxy

When I want to get a maps on my browser. Kibana don't show the map and send this error message :
Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' 'nonce-...". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution.
So I try to add CSP header in my Nginx config but it doesn't work.

Some ideas ?

Hello,

It's a little hard to know for sure since the proxy setup will have more to do with a specific nginx configuration than Kibana. Having said that, perhaps this discussion w/ links might point you in the right direction?
