WireGuard doesn't work with DNSCrypt

[LukaTCE]

Hi SimpleDNSCrypt doesn't work with local hosted WireGuard VPN on router/gateway
Connection works just it don't change DNS
With old original SimpleDNSCrypt from bitbeans even internet connection don't work which is based on old DNSCrypt
On FritzBox there is no specific settings for wireguard DNS. DNS can be changed for connection without VPN and with VPN
WireGuard Config are this
Address = 192.168.178.201/24
DNS = 192.168.178.1, fritz.box

AllowedIPs = 192.168.178.0/24, 0.0.0.0/0
Endpoint = Randomdomain.myfritz.net:58658
