Socket + SSL does not work PHP

Question

Good morning, I have a system that uses a chat created by me and your communication by socket, all in php.

The point is, I asked hostgator install the SSL in the domain, it has been installed and works normally, but when I try to use the socket, return the following errors to me:

app.js? v=1484568422:59 Mixed Content: The page at 'https://vendemoda.com.br/sandbox/admin_responsivo/index.php' was Loaded over HTTPS, but attempted to connect to the insecure Websocket endpoint 'Ws://192.185.220.81:9009/'. This request has been blocked; this endpoint must be available over WSS. (Anonymous) @app.js? v=1484568422:59

app.js. v=1484568422:59 Uncaught Domexception: Failed to Construct 'Websocket': An insecure Websocket Connection may not be initiated from a page Loaded over HTTPS. at https://vendemoda.com.br/sandbox/admin_responsivo/js/app.js?v=1484568422:59:16

Who can, please help me.
