Problem with Pop3Client

            client.Connect("pop.gmail.com", 995, true);
            client.Authenticate(Email, Password); // throws: MailKit.Security.AuthenticationException: „Authentication failed.”
            var count = client.GetMessageCount();
            StackPanel mailPanel = MailPanel.Children.OfType<StackPanel>().First();
            mailPanel.Children.Clear();
            foreach(MimeMessage message in client.GetMessages(Enumerable.Range(0, 100).ToList()))
            {
                mailPanel.Children.Add(new Label { Content = message.Subject });
            }
        }
        // LoginPage.xaml.cs
        // Works perfectly, it has the exact same credentials
