Hello,

Since last night the websocket no longer works but only from an IOS device, in particular tested on a MAC. Everything seems to work from a PC. The Let’s Encrypt SSL certificate is valid.  
Firewall port checking is OK.

WebSocket connection to ‘wss://XXXXXXXXXXXXXXX.COM:3050/socket.io/?id=…’ failed:

mediasoup config.js :

Thanks for help

Hi

What is your solution to this as we are experiencing this issue as well.

Safari and Chrome issue but Firefox is fine.

Thanks
