Hello!
If you are using a QWebSocketServer you can call close() when a new connection
has been established and call listen() again when the currently-connected
socket disconnects.
Attached is a toy example of doing so.

Subject: [Interest] QWebSocket limit connection
Hello all,
I am using a QWebSocket in order to communicate between a browser and an
application which works fine.
In my specific use case I want to prevent more than one browser to connect to
the application.
Is there a way to decline further connections after one has been established ?
Thanks in advance,
best
Alex
