Проблема аутентификации FreeRadius

Возникла странная проблема с pptp и freeradiuss на VPS CentOS 6.4. У меня 1 VPS в качестве основного сервера freeradius. 2 других VPS используются для подключения через pptp с использованием удаленного свободного радиуса для аутентификации. 1 VPS работает нормально, но другой при попытке подключения дает следующее:

Может ли кто-нибудь указать мне правильное направление, чтобы исправить это, пожалуйста?
