Signalr connection problem

JavaScript
1

every time i try to invoke the signalr connection i get a error message:

Unhandled Rejection (Error): Cannot send data if the connection is not in the ‘Connected’ State.

while the first thing i do is to start the connection:

      useEffect(() => {
      
        const Connection = new HubConnectionBuilder()
        .withUrl('https://localhost:44332/chatHub')
        .withAutomaticReconnect()
        .build();
        setNewConnection(Connection)
        
        Connection.start().then(result => { console.log("connected")});
        
Connection.invoke("JoinGroup", "PrivateGroup");
 Connection.on("ReceiveMessage", (message) => {
        setTestName(message)})
        },[]);

i get a message in the console saying: connected wich means that Signalr is connected
so i dont understand why it has problems sending data if it would be connected.

the backend code is also completely fine.
