TLS 1.2+ is not supported

[karelmaxa]

Currently, only TLS 1.0 is supported for websocket communication. The following error is thrown when a client (e.g. Wren:IDM) supports only never ciphers (TLS 1.2+):

javax.net.ssl|ERROR|D2|OpenICF Client Grizzly worker thread(5)|2024-11-07 13:06:28.918 GMT|TransportContext.java:370|Fatal (PROTOCOL_VERSION): The server selected protocol version TLS10 is not accepted by client preferences [TLS12] (
javax.net.ssl.SSLHandshakeException: The server selected protocol version TLS10 is not accepted by client preferences [TLS12]

It is an issue of the WebSocketListener library, there is an official issue: vtortola/WebSocketListener#138.
