T46G openvpn

Hi,

i have a problem with my Yealink T46G Firmware version: 28.73.193.50
On my computer the openvpn works fine.

If i upload the configuration file i get in my logs of the vpn server:

Nov 17 18:00:50 openvpn[402]: TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Nov 17 18:00:50 openvpn[402]: TLS Error: TLS handshake failed

my config file that i download from my pfsense openvpn server is.
Can anyone help me?

dev tun
persist-tun
persist-key
cipher AES-256-CBC
auth SHA1
tls-client
client
resolv-retry infinite
remote REMOTE-IP-ADRES 1194 udp
ca /config/openvpn/keys/ca.crt
cert /config/openvpn/keys/client1.crt
key /config/openvpn/keys/client1.key
tls-auth /config/openvpn/keys/ta.key 1
ns-cert-type server

in the syslog i see everytime Unroutable control packet received from the ip i want to connect to.
anybody has any ideas?
