L2TP/IPsec VPN help

Hi,
Over the weekend I have been trying to setup a vpn on my RB.
I have followed this guide: https://manuth.life/l2tpipsec-vpn-server-mikrotik-routeros/

But I get this error:
IPsec Error.png
This occures when trying to connect to the Local AND External (ISP) IP address.

Here is my client config:

(The Preshare key is correct)

I have looked at other forum posts and tried what they suggest and still no luck.
Thanks for you help.

Choose L2TP/IPsec manually as Type of VPN in the Windows client instead of Automatic. And post your Mikrotik side config following the instructions in my automatic signature. “I’ve followed the instructions in xxx” doesn’t give enough information regarding the resulting configuration.
