Correct logic to reconnect in SignalR with HubConnection

private async Task<bool> ConnectToSignalRServer()
{
    bool connected = false;
    try
    {
        Connection = new HubConnection("server url");
        Hub = Connection.CreateHubProxy("MyHub");
        await Connection.Start();

        //See @Oran Dennison's comment on @KingOfHypocrites's answer
        if (Connection.State == ConnectionState.Connected)
        {
            connected = true;
            Connection.Closed += Connection_Closed;
        }
        return connected;
    }
    catch (Exception ex)
    {
        Console.WriteLine("Error");
        return false;
    }
}

private async void Connection_Closed()
{
    if(!IsFormClosed) // A global variable being set in "Form_closing" event of Form, check if form not closed explicitly to prevent a possible deadlock.
    {
        // specify a retry duration
        TimeSpan retryDuration = TimeSpan.FromSeconds(30);

        while (DateTime.UtcNow < DateTime.UtcNow.Add(retryDuration))
        {
            bool connected = await ConnectToSignalRServer(UserId);
            if (connected)
                return;
        }
        Console.WriteLine("Connection closed")
    }
}
