Get the cookie code from the web-request

Question

I tried the following method to log into Facebook to get cookies, but I couldn't get cookies.
What is the problem that occurred and how is it resolved.

Dim cookieJar As New Net.CookieContainer()
            Dim username As String = "username"
            Dim password As String ="password"
            Dim cookieContainer As CookieContainer
            Dim bytes As Byte()
            Dim httpWebRequest As HttpWebRequest
            Dim s As String = "lsd=AVpRTdGdsWI&jazoest=2975&m_ts=1647910928&li=ECA5YmmANHURTJaXGqilTsJc&try_number=0&unrecognized_tries=0&email=" & username & "&pass=" & password & "&login=%D8%AA%D8%B3%D8%AC%D9%8A%D9%84+%D8%A7%D9%84%D8%AF%D8%AE%D9%88%D9%84&bi_xrwh=0"
            cookieContainer = New CookieContainer()
            bytes = utf8Encoding.GetBytes(s)
            httpWebRequest = CType(WebRequest.Create("https://mbasic.facebook.com/login.php?refsrc=https%3A%2F%2Fmbasic.facebook.com%2F&lwv=100&login_try_number=1&refid=8"), HttpWebRequest)
            httpWebRequest.Method = "POST"
            httpWebRequest.Proxy = Nothing
            httpWebRequest.Host = "mbasic.facebook.com"
            httpWebRequest.Headers.Add("Upgrade-Insecure-Requests", "1")
            httpWebRequest.ContentType = "application/x-www-form-urlencoded"
            httpWebRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:59.0) Gecko/20100101 Firefox/59.0"
            httpWebRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"



            httpWebRequest.CookieContainer = cookieContainer
            httpWebRequest.Referer = "https://mbasic.facebook.com/login/?next&ref=dbl&fl&refid=8"
            httpWebRequest.KeepAlive = True
            httpWebRequest.ContentLength = CLng(bytes.Length)
            Dim requestStream As Stream = httpWebRequest.GetRequestStream()
            requestStream.Write(bytes, 0, bytes.Length)
            requestStream.Close()
            httpWebResponse = CType(httpWebRequest.GetResponse(), HttpWebResponse)
            cookieContainer.Add(httpWebResponse.Cookies)

            Dim streamReader As StreamReader = New StreamReader(httpWebResponse.GetResponseStream())
            Dim text As String = streamReader.ReadToEnd()
            streamReader.Close()
             RichTextBox1.Text = text
