How can I debug it?
Every time I visit the website for the first time, it refreshes itself. You can see it in the video. Unfortunately, all day I was looking and I can not fix the problem.

It's worth taking a look at

[00:23:19 INF] Executing endpoint 'Blazor disconnect'

[pranavkm]

Could you bump up the LogLevel to Debug? It might have further details on why the circuit failed to reconnect.

I suspect there's a memory leak somewhere.
My code _Host.cshtml

    var GetIP = "";
    if (Request.HttpContext.Connection.RemoteIpAddress != null)
        GetIP = Request.HttpContext.Connection.RemoteIpAddress.ToString();

    var GetAgent = Request.Headers["User-Agent"].ToString();
    var GetCookies = new List<AppState.Cookies>();

    foreach (var cookie in  Response.HttpContext.Request.Cookies) {
        GetCookies.Add(new AppState.Cookies {
            Name = cookie.Key,
            Value = cookie.Value
        });
    }

    var GetSession = GetCookies.SingleOrDefault(x => x.Name == "SESSION").Value;

GetCookie is a cookie object.
While debugging, it is done once when we enter the page.

    <component type="typeof(App)" render-mode="ServerPrerendered" param-GetIP="@GetIP" param-GetAgent="@GetAgent" param-GetCookies="@GetCookies" param-GetSession="@GetSession"/>

Passes the following parameters to app.razor

Code app.razor

@code{

    [Parameter] 
    public string GetIP { get; set; } = "";
    [Parameter] 
    public string GetAgent { get; set; } = "";
    [Parameter]
    public List<AppState.Cookies> GetCookies { get; set; } = new List<AppState.Cookies>();
    [Parameter] 
    public string GetSession { get; set; } = "";

    protected override async Task OnInitializedAsync() 
    {
        AppState.CurrentUserSession = GetSession;
        AppState.SetHttp(GetIP, GetAgent, GetCookies);
    }
}

First polling:

Everything is fine, it works
Another magic loop:

The list is null, best of all. The rest of the variables are OK. Only the letter is null, detects two records but is null.

@Alerinos are you able to provide a minimal app that reproduces the issue? It looks like there's a few different issues you're running in to, and we should start by tackling the blazor circuit disconnect.

@pranavkm
I can share my entire project with you, you will be able to run it and check what's wrong. Do you have a discord? Are you ready to write to me? Alerin#5559

Thanks, but a minimal app is preferable. It helps narrow down the problem to an issue to the framework and removes any user issues as possible sources of the issue.
