VPN desconectando

Olá. Optei por substituir o Windows 10 pelo Linux Mint 19.2 Cinnamon. Está tudo quase tudo perfeito, senão a necessidade que eu tenho de acessar esporadicamente a VPN do meu trabalho. Utilizo NetExtender para realizar a conexão e ocorre que após de aproximadamente 3 minutos é desconectado, sendo que neste período em que está conectado não consigo pingar nenhum IP da rede. Se alguém puder me ajudar ou tiver a solução, desde já agradeço. Segue abaixo o log gerado pelo NetExtender.
