SignalR client receives Information: Connection disconnected from hub

Question

Hi everyone,

I created a signalR JavaScript client that needs to communicate with a hosted signalR server (from Playfab). I successfully created the signalR client and connected it with the server, but the problem that I'm facing is that the connection doesn't stay open more than 30 seconds even though I subscribe to events.

Here are the messages between the client and server. After one ping, the server sends a close message.
How can I prevent this from happening?

Here is how the connection is created

connection = new signalR.HubConnectionBuilder()  
    .withUrl(`url`, {  
      withCredentials: false,  
      httpClient: new SignalRClient(),  
      headers: {  
        'X-EntityToken': entity.EntityToken,  
      },  
    })  
    .build()  
  
await connection.start()
