Wireguard and sonos

Hi,

I’ve been trying to setup wireguard properly. I used @DrZzs youtube and @frenck tutorials. But I guess I am not really getting it somehow…

What does not seem to work is SONOS. I use their app quite a lot, but I always have to switch off wireguard to use it… I was assuming that this would work all together…without switching VPN off or on.

The setup seems to be working partly…
I don’t have those annoying adds (thanks to ad-guard) on my phone or laptop.

Not really sure if it has anything to do with it, but I manage (not) to access the next things when VPN is on:

https://hassio.local:8123 on the laptop (SSL error included but it works) On my android device it does not work.
Can’t acces server address 172.27.66.1 which I setup in wireguard on the laptop nor mobile. Not sure if I should suppose to be able to do this…
Accessing Hassio with the fixed (static IP) 192.168.178.xx also works on the laptop (with SSL error) but not on the mobile. It just gives me an DNS_PROBE_FINISHED_NXDOMAIN error.

[mysecret].duckdns.org:8123 always works on all the devices.

I’ll share my wireguard configuration… Maybe someone can tell me what I am doing wrong…or should be doing?
