✅ Groups & Clients in SignalR not taking requests.

I have 2 Hub tasks, 1. Connect 2. Send I save all connections that are being sent to connect with a game code, and store them in a group.. Like this:

public async Task Connect(string gameId)
{
    await Groups.AddToGroupAsync(Context.ConnectionId, gameId)
}

public async Task Send(string gameId)
{
    await Clients.Group(gameId).SendAsync("Testing");
}

public async Task Connect(string gameId)
{
    await Groups.AddToGroupAsync(Context.ConnectionId, gameId)
}

public async Task Send(string gameId)
{
    await Clients.Group(gameId).SendAsync("Testing");
}

I tried doing this, but it simply won't work? I also tried storing away a client connection ID and not go through groups, but I am not able to send any requests down to my Javascript part? It works if I use Clients.All.SendAsync(), but nothing else..?

Its quite simple:

public class GameHub : Hub
{
    public async Task Connect(string gameId)
    {
        await Groups.AddToGroupAsync(Context.ConnectionId, gameId)
    }

    public async Task Send(string gameId)
    {
        await   Clients.Group(gameId).SendAsync("Testing");
    }
}

public class GameHub : Hub
{
    public async Task Connect(string gameId)
    {
        await Groups.AddToGroupAsync(Context.ConnectionId, gameId)
    }

    public async Task Send(string gameId)
    {
        await   Clients.Group(gameId).SendAsync("Testing");
    }
}

If I try sending with await Clients.All.SendAsync("Testing"); in the Send method, it works as intended...

Did you verify Connect is called at all? The code here is valid. There's not much people can do here unless you follow the steps to debug

I actually managed to fix it? It was quite weird why it was happening? I called Connect on 1 page, and when I was redirected to a new page right after the connection ID was wrong?? It seemed like it wasn't fully started before trying to run the first "Connect" method..

They mentioned to have fixed it unless it's a random thing?
