Внезапно все звонки на мои веб-сервисы получают эту ошибку:

До того, как все было в порядке :( Кто-нибудь знает, где проблема и как ее решить?
Большое спасибо!

Вот один из моих веб-методов:
[WebMethod(EnableSession = true)]
public CommonResult ActivityLog(string kioskID, string KTID,
string activityType, int errorCodeFromIncentOne, string msgFromIncentOne, DateTime kioskTime)
{
XMLParser parser = new XMLParser(Server.MapPath(Constant.XML_CONFIGURATION_FILE_PATH));
CommonResult result = new CommonResult();
try
{
AccountDAO accountDAO = new AccountDAO();
ActivityLogDAO activityLogDAO = new ActivityLogDAO();
KioskDAO kioskDAO = new KioskDAO();
// check if this kiosk is existed
if (!kioskDAO.IsKioskIDExisted(kioskID))
{
result.ErrorCode = Constant.ERROR_CODE_KIOSKID_NOT_EXISTED;
result.Message = "abc";
return result;
}
// check if this KTID is existed
if (!accountDAO.IsKTIDExisted(KTID))
{
result.ErrorCode = Constant.ERROR_CODE_KTID;
result.Message = "abc";
return result;
}
// check if this customer already logged for today
if (activityLogDAO.IsLoggedForToday(KTID, DateTime.Now))
{
result.ErrorCode = Constant.ERROR_CODE_LOG_LIMIT;
result.Message = "abc";
return result;

// begin log this activity to database
activityLogDAO.ActivityLog(KTID, kioskID, kioskTime);

result.ErrorCode = Constant.ERROR_CODE_SUCCESS;
result.Message = "abc";
return result;
}
catch (Exception e)
{
result.ErrorCode = Constant.ERROR_CODE_SYSTEM_ERROR;
result.Message = "abc";
return result;
}
}
