Safari Refused to connect to wss due to missing Content-Security-Policy (CSP)

[dennisat]

Only Safari is complaining about the CSP. The consoled error is:

Refused to connect to wss://example.com/socket.io/?EIO=4&transport=websocket because it appears in neither the connect-src directive nor the default-src directive of the Content Security Policy.

Tried add the<meta http-equiv="Content-Security-Policy" content="connect-src https: wss:;"> but still something is missing.

Any suggestion?
