[solved] Multisite-to-Multisite won't work

[Bob.Dig]

I want to create a WireGuard Multisite-to-Multisite Network, everyone should be connected to everyone.

I have 3 Locations:

A= pfSense @ VPS
B= Windows @ VPS
C= pfSense @ Home

Most of it works except A and B never connect. I have checked the configs over and over again and can't find the problem (with my amateur knowledge).

Edit: Solved. Had to set keep alive on the windows host, probably because I had changed to much other stuff beforehand.
