I am trying to setup my deco Xe75 system to use NordVPN using the app. However then trying to upload the config file i get an error. Installation failed. Verify the configuration file and try again (my translation). I tried different config files for UDP and TCP and different server. This is an example config file i downloaded from NordVPN:

 

client
dev tun
proto udp
remote 178.239.164.131 1194
resolv-retry infinite
remote-random
nobind
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
persist-key
persist-tun
ping 15
ping-restart 0
ping-timer-rem
reneg-sec 0
comp-lzo no
verify-x509-name CN=uk898.nordvpn.com

remote-cert-tls server

auth-user-pass
verb 3
pull
fast-io
cipher AES-256-CBC
auth SHA512
<ca>
-----BEGIN CERTIFICATE-----
{CERTIFICATE}
-----END CERTIFICATE-----
</ca>
key-direction 1
<tls-auth>
#
# 2048 bit OpenVPN static key
#
-----BEGIN OpenVPN Static key V1-----
{key}
-----END OpenVPN Static key V1-----
</tls-auth>

Any thoughts what is wrong?
