Httpselfhostserver not binding any BaseAddress

Question

I use HttpSelfHostServer and I want to bind it on unique specified prefix.

public StatServer(string prefix)
{
    if (string.IsNullOrEmpty(prefix))
    {
        Console.WriteLine("Can't use empty prefix");
        return;
    }
    var configuration = new HttpSelfHostConfiguration(new Uri($"http://perchik:8080"))
    {
        HostNameComparisonMode = HostNameComparisonMode.Exact
    };
    SetRoutes(configuration);
    configuration.Formatters.Clear();
    var jsonMediaTypeFormatter = new JsonMediaTypeFormatter {Indent = true};
    configuration.Formatters.Add(jsonMediaTypeFormatter);
    configuration.Formatters.Add(new FormUrlEncodedMediaTypeFormatter());
    _server = new HttpSelfHostServer(configuration);
}

Before I start the StatServer I run command as Administrator: "netsh http add urlacl url=http://+:8080/ user=machine\user"

And "ERR_NAME_NOT_RESOLVED" is appear when i try "http://perchik:8080/controller/id" or "http://localhost:8080/controller/id".

I want to use prefix like perchik-placeholder, but nor random prefix neizer perchik-word doesn't work P.S.

If I remove HostNameComparisonMode = HostNameComparisonMode.Exact line from code above: "http://perchik:8080/controller/id" is still not worked, but "http://localhost:8080/controller/id" is worked.
