WebGl Client not connect to Linux Server by websocket transport

[NotBugThisFicha]

I created Linux dedicated ssl sertifacted server and webGl client, both with websocket transport and unity netcode for GO, and use 443 port with secure connection on client, but i can connect in unity editor, but not as client build on server, in console webpage i see error: WebSocket connection to 'wss://https//{name domain}{Path}:443/' failed:
Why domain prefics protocol before wss, is https? there must be wss://{name domain}{Path}:443/
