请问下大神，这是哪里错了呢。网站后台有配置信任登录，今天去QQ互联申请了，测试出现这个问题。

后台cs：
 protected void SkipQQOpenId()
        {
            Member member;
            member = member = new Member(UserRole.Member);
            if (HiContext.Current.ReferralUserId > 0)
            {
                member.ReferralUserId = new int?(HiContext.Current.ReferralUserId);
            }
            member.GradeId = MemberProcessor.GetDefaultMemberGrade();
            HttpCookie cookie = HttpContext.Current.Request.Cookies["NickName"];
            if (cookie != null)
            {
                member.Username = HttpUtility.UrlDecode(cookie.Value);
            }
            if (string.IsNullOrEmpty(member.Username))

            }
