Please, tell us how to recreate the issue in as much detail as possible.

Secure WebSocket connection (wss:// protocol) does not work on iOS platform at all. On Android it works pretty well, same from test client browser, so I'm sure that server configuration is OK.

iOS socketio client cannot establish connection. Maybe it is related with TLS support on iOS?

Is there any code involved?

Just use simple constructor with URL wss://.... Options are: transports: ["websocket"]

That's all.
