Asus rt-ac68u OpenVPN not connecting with iPhone

[levyrj]

I am able to connect to my VPN server via my macbook but not my iphone.
Here is my setup:
Asus RT-AC68U configured as an OpenVPN server

Exported OpenVPN config file -> OK
Imported OpenVPN config file on Macbook -> using Viscosity vpn client -> SUCCESSFULLY connects
Imported *same* OpenVPN config file on iPhone 6s ios 10.2 -> config file imports but connection FAILS (timesout)

Error log from Asus when trying to connect from iPhone:

This is your probelm: TLS Error: TLS handshake failed
Check "Extra HMAC Authorization (tls-auth)" have right settings.
Usually server have "0" and clients have "1"
Then must have same "Static Key" on both ends.
