Клиентское соединение OpenWRT StrongSwan IPsec (XAuth-аутентификация пользователя (меня) не удалась)

Я пытаюсь настроить маршрутизатор OpenWRT для подключения к удаленному серверу VPN. Учетные данные, которые у меня есть, верны, но по какой-то причине соединение не проходит проверку подлинности на маршрутизаторе. Вот мои конфиги

/etc/ipsec.conf

conn l2tpconn
  keyexchange=ikev1
  authby=xauthpsk
  xauth=client
  left=%defaultroute
  leftsourceip=%config
  leftfirewall=yes
  leftauth=psk
  leftauth2=xauth
  leftid=user
  right=<server_ip>
  rightsubnet=0.0.0.0/0
  rightauth=psk
  rightauth2=xauth
  auto=add

/etc/ipsec.secrets

%any <server_ip> : PSK 'secret'
'user' : XAUTH 'password'

Может быть, это что-то простое, и я скучаю по нему, но если у всех вас есть какие-либо предложения, которые были бы очень полезны. Благодарю.
