I have two sites on the same Nginx server.

The site www.example.com contains HTTP headers, but not the analytics.example.com

When I go to the analytics.example.com site there is an error message in the console :

Mixed Content: The page at 'https://analytics.s1biose.com/' was loaded
over HTTPS, but attempted to connect to the insecure WebSocket
endpoint 'ws://analytics.example.com:7890/'. This request has been
blocked; this endpoint must be available over WSS.

I think this message is displayed because of the HTTP header:

add_header Content-Security-Policy "default-src * data: 'unsafe-eval' 'unsafe-inline'" always;

from www.example.com

But why analytics.example.com inherits HTTP header from www.example.com ?

The HTTP header should be applied to www.example.com but not to analytics.example.com because the 2 sites are totally different.

How to correct this problem ?
