Raspberry Pi as wireguard client not working :(

Hi everybody,

I'm stuck here: I can't get a wireguard client on my raspberry pi to work.
I've set up some other clients - all were straight forward: read the conf file with the wireguard client, connect, done.

Now what I've done on my raspberry pi:

Set up a new wireguard peer (remote access to server) in the unraid VPN settings, unzipped the zip file and copied the .conf file to my raspi.

On my raspi:
sudo apt install wireguard
copy .conf file to /etc/wireguard/wg0.conf
 

phil@audrey:~ $ sudo wg-quick up wg0
[#] ip link add wg0 type wireguard
[#] wg setconf wg0 /dev/fd/63
[#] ip -4 address add 10.253.1.7/32 dev wg0
[#] ip link set mtu 1412 up dev wg0
[#] ip -4 route add 192.168.187.16/32 dev wg0
[#] ip -4 route add 10.253.1.1/32 dev wg0

Now this looks fine to me. But then:
 

phil@audrey:~ $ ping -c 3 10.253.1.1
PING 10.253.1.1 (10.253.1.1) 56(84) bytes of data.

--- 10.253.1.1 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2040ms

Now I'm no networking whiz, so this is as far as debugging this went:

Pinging myself with the 10.* IP address works:
 

phil@audrey:~ $ ping -c 3 10.253.1.7
PING 10.253.1.7 (10.253.1.7) 56(84) bytes of data.

some more:

Now I'm stuck. Any help is appreciated.
