[Tailscale] Can't connect VPS to local network? (lemmy.dbzer0.com)

I set up Headscale and Tailscale using Docker on a VPS, which I want to use as my public IPv4 and Reverse Proxy to route incoming traffic to my local network and e. g. my home server. I also set up Tailscale using Docker on my home server and connected both to my Headscale server.
I am able to ping on Tailscale container from the other and vice versa and set up --advertise-routes=192.168.178.0/24 on my home server as well as --accept-routes on my VPS, but I can't ping local IP addresses from my VPS. What am I missing?
Both container are connected to the host network, I have opened UDP ports 41641 and 3478 on my VPS.

Are you sure Tailscale in Docker is creating a wg0 interface? Because I got a working connection between my smartphone and my home server and the home server is not showing any interface related to Tailscale?

default via 192.168.178.1 dev ens18 
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 
192.168.178.0/24 dev ens18 proto kernel scope link src 192.168.178.178

Are you running it in a container? Then you'll be seeing the docker0 interface as you see there, and the container will route through that.

Yes I'm running it on Docker and therefore have the docker0 interface.
