Site to Site VPN - IPSEC not working AC1600 VC321-G2h

Hi Community,
I'm trying to get a simple IPSEC site to site VPN working on my VC321-G2h (AC1600).
The AC1600 is connected to the internet (VDSL) and working fine. I'm not using the 4G failover feature (no SIM card installed).
I try to setup a IPSEC site to site VPN to my data centre where this client has their servers. The router at the datacentre is a Cyberoam.
The Cyberoam has several IPSEC site to site VPN's working with various other routers (Draytec, Sonicwall etc)
I have tried various combinations of settings but cannot get the VPN to work.
The error log in the Cyberoam reports : "The system did not accept any proposal received. Need to reconfigure the connection on either of the ends"
The system logs on the TP-Link are next to useless and don't offer any information even in debug mode.
There must be something basic I'm missing on the TP-link that is stopping it. I have watched the videos and read heaps of articles and it seems pretty straight forward and should just work?
Anyone else successfully get a site to site VPN working with TP-Link AC1600?
