Недопустимый или просроченный двоичный токен безопасности: null

Почему сессия заканчивается сразу после получения ответа на запрос аутентификации?

Я получаю двоичный токен, как описано здесь https://developer.sabre.com/docs/read/soap_basics/Authentication . После получения токена я использую тот же токен для поиска рейса, но получаю сообщение об ошибке вроде:

com.sabre.universalservices.base.security.AuthenticationException:
errors.session.USG_INVALID_SECURITY_TOKEN

`

Мой код для поиска рейса:

$wsdl = "http://webservices.sabre.com/wsdl/tpfc/OTA_AirAvailLLS2.3.0RQ.wsdl";
$sabreSoapServer = "https://webservices3.sabre.com";
