Webgl - Networked game - process of uploading - errors - questions

Hi I am making a multiplayer game with unity and have a couple of doubts.

First

the game consists of a bunch of clients, that connect to a single dedicated master Client (also a unity game on its own: hereafter referred to simply as 'server'). All of these clients speak to each other by relaying their information through this server using the LLAPI. I have made the game, which thus far is just a little man, some camera work and a chat system, work in webgl while speaking locally to my server.

I have now tested uploading it to Itch.io which works locally, as in speaking to '127.0.0.1'. However it does not work in firefox or edge. as it gets the following errors:

"exception thrown: SecurityError: The operation is insecure.,_JS_UNETWebSockets_SocketCreate@blob:https://v6p9d9t4.ssl.hwcdn.net/019f3d09-29d8-45d6-9b26-e85868c74456:2:234689" - unityLoader.js

its as soon as this code is run the error comes

 Debug.Log("connecting...");
         // does player have a name?
         string pName = GameObject.Find("NameInput").GetComponent<InputField>().text;
         if (pName == "")
         {
             Debug.Log("Enter a name");
             return;
         }
 
         playerName = pName;
 
         NetworkTransport.Init();
         ConnectionConfig cc = new ConnectionConfig();
 
         reliableChannel = cc.AddChannel(QosType.Reliable);
         unReliableChannel = cc.AddChannel(QosType.Unreliable);
 
         HostTopology topo = new HostTopology(cc, MAX_CONNECTION);
 
         hostId = NetworkTransport.AddHost(topo, 0);
 
         connectionId = NetworkTransport.Connect(hostId, "127.0.0.1", port, 0, out error);
 
         connectionTime = Time.time;
 
         isConnected = true;
 
         NetworkServer.useWebSockets = true;
 
         Debug.Log("connected");

Secondly

I would like to ask how it is I would go about uploading the entire game to the internet. as Far as I can understand I could upload the server to a host and then guide the clients to that URL and that should work? So could I for example upload the server to AWS and then just have my clients connect to it from any browser? has anyone tried doing this? I love to hear what sort of solution people use for this.

e.g:

 connectionId = NetworkTransport.Connect(hostId, "URL_pointing_to_the_server", port, 0, out error);
