Flint 3 WireGuard and HA

Hi all,
I’m no expert in VPN or tunnelling but this is frustrating me.
I have both Flint 2 and Flint 3
Virgin media modem in bypass mode.
Home assistant connected by LAN

So if I set up flint 2 and configure the WireGuard server then connect to my flint 2 with Slate 7 (roaming away from home) all works fine.
I can connect to HA with my duckDNS server details perfectly.

Now same on the flint 3 sever and client connect fine except HA will just not connect.

I’ve tried all types of WireGuard settings and configs but now I am lost.

Am I missing something that might of changed between routers?
Thanks
Brian
