secureMode QWebSocketServer stops accepting connections after multiple failed ws:// connection attempts

A secureMode QWebSocketServer working normally with wss:// connections. stops accepting connections after multiple failed ws:// connection attempts. Connections that were already open still communicate properly.

Consistently, after about 10 to 50 attempts to communicate via ws:// (I tried ws:// attempts at about 1sec interval), the server stops emitting newConnection signals when presented with correct wss:// connections. No error signals emitted.

I think this is an extension of QTBUG-42283 and QTBUG-44866
