Websocket connection doesn't work on Safari desktop browser, and all browser at iOS.

https://cdnjs.cloudflare.com/ajax/libs/socket.io/1.4.5/socket.io.min.js WebSocket connection to 'wss://{domain.com}/socket.io/?EIO=3&transport=websocket&sid=OwKaDx900YpSRDC7AAC_' failed: WebSocket is closed before the connection is established.

Is there any solution that works around it?

Thank!
