In a js script I use a ddp client to connect to my meteor app. And suddenly I got this error
Refused to connect 'wss://app.backtocart.co/websocket' because it violates the following Content Security Policy directive: "default-src https: data: 'unsafe-inline' 'unsafe-eval' ". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback
What is this? I meet this first time. How can I fix it?
