Unity LLAPI HTTPS webSoket ->WSS

Hello. I am developing a game for WebGL (social network). They are using HTTPS only. For the network I use LLAPI (since HLAPI does not support WebGL). When I tested it on HTTP, it worked. However, when I loaded the game and went through HTTPS, the buttons "start client" got the error: Uncaught DOMException: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.

   if ( GUI.Button( new Rect(10, 70, 250, 30), "start server" ) )
                         {
                                 _isStarted = true;
                                 _isServer = true;
                                 NetworkTransport.Init();
 
                                 HostTopology topology = new HostTopology(m_Config, 2);
                                 m_WebSocketHostId = NetworkTransport.AddWebsocketHost(topology, port, null);           //add 2 host one for udp another for websocket, as websocket works via tcp we can do this
                                 m_GenericHostId = NetworkTransport.AddHost(topology, port, null);
                 Debug.LogError(topology.MessagePoolSizeGrowthFactor+";"+ topology.ReceivedMessagePoolSize+";"+ topology.SentMessagePoolSize+";"+m_Config.FragmentSize+";"+m_Config.MaxCombinedReliableMessageCount+";"+m_Config.MaxCombinedReliableMessageSize+";"+m_Config.MaxSentMessageQueueSize+";"+m_Config.WebSocketReceiveBufferMaxSize);
             }
 #endif
                         if (GUI.Button(new Rect(10, 100, 250, 30), "start client"))
                         {
                                 _isStarted = true;
                                 _isServer = false;
                                 NetworkTransport.Init();
 
                                 HostTopology topology = new HostTopology(m_Config, 2);
                                 m_GenericHostId = NetworkTransport.AddHost(topology, 0); //any port for udp client, for websocket second parameter is ignored, as webgl based game can be client only
                                 byte error;
                                 m_ConnectionId = NetworkTransport.Connect(m_GenericHostId, ip, port, 0, out error);
                 Debug.LogError(error + ";");
             }

All that I have found, indicating that LLAPI can not use WSS. But HTTPS uses only WSS. Can you please tell me what to do? I do not want to change to another technology LLAPI after weeks of development

For the certificate, I use cloudflare

I do not use Unity matchmaking. The master server is written in LLAPI and is on my VDS. There is also a build (index.html).

string ip = " XXX.XXX.XXX.XX ";//VDS IP

P.S. Sorry for my English. It's not me. This google translate
