I was trying to connect front end and back end to the server, it was connected but when the web app in idle for 45 minutes it gets disconnected, i want my web app to not get disconnect to the SignalR hub, I tried lots of code and read lots of documentation but i cant fix that issue

this was the code i used in my backend server

Starup.CS

services.AddSignalR(hubOptions =>
{
hubOptions.KeepAliveInterval = TimeSpan.FromSeconds(30);
});

app.MapHub<NotificationSignalrHub>(pattern: "/NotificationHub");

SignalRHub.CS

public async Task HandShakeToNotificationHub(UserConnection userConnection)
{
try
{
await Groups.AddToGroupAsync(Context.ConnectionId, GroupName);

    bool isOperationDone = adding the connectionid to the Database;
    if (isOperationDone)
    {
        await Clients.Group(GroupName).SendAsync("HandShakeToNotificationHub", "System", $"{userConnection.UserEmail} has been connected.");
    }
}
catch (Exception)
{
    throw;
}

}

public async Task SendMessage(string message)
{
try
{
var mar = getting the connection id from the Database;
if (mar is not null)
{
await Clients.Group(GroupName).SendAsync("ReceiveNotification", message);
}
}
catch (Exception ex)
{
throw;
}
}

hubOptions.KeepAliveInterval = TimeSpan.FromSeconds(30);

Did you also change the ServerTimeout on the client side?

Get logs so we can see why the connection disconnected:
