IPsec tunnel from OPNSense router to OPNsense router on HyperV no connection

[Nout]

Hi, I'm absolutely new to OPNsense and trying to get an IPsec tunnel working between 2 VM's.
Trying equals not working in this case....
I followed this https://docs.opnsense.org/manual/how-tos/ipsec-s2s-route.html to to the letter.
After doing this I would guess it should be possible to ping both sides of the IPsec tunnel? (in this case 10.111.1.1 and 10.111.1.2) In my case it isn't.
Is there anyone who could give me a hint what to look at?

update:
I think I have another problem. Busy testing I discovered I'm not able to ping the gateway and the WAN of the other OPNsense router.
