Erro VPN filial " Operation not permitted"

Srs.

BOm dia!

A vpn de uma determinada filial esta funcionando blz, mas todo dia cedo é preciso reboot no servidor para ela voltar a funcionar (ja tentei restart no servico openvpn e nao obtive sucesso). axo que o cliente esta desligando a maquina anoite, ma isso nao seria problema pois em outras filiais acontece a mesma coisa e a vpn volta a funcionar blz... dei uma olhada no log e apresentou a seguinte msg de erro:
