You can't access your instance because the only way to reach the container is through the VPN server (as it should be). You have to open a hole in the container's firewall to access it through the local network.

In the [Interface] section in your Wireguard configuration, add the following lines:

PostUp = DROUTE=$(ip route | grep default | awk '{print $3}'); HOMENET=172.16.0.0/12; ip route add $HOMENET via $DROUTE;iptables -I OUTPUT -d $HOMENET -j ACCEPT; iptables -A OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT

PreDown = HOMENET=172.16.0.0/12; ip route delete $HOMENET; iptables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT; iptables -D OUTPUT -d $HOMENET -j ACCEPT

Replace the value of HOMENET with whichever network you're accessing it from, mine's set to the docker network because it's behind an nginx reverse proxy.
