Can not reach containers web-ui via lxd hosts IP address

I have a container running on my laptop which serves a webinterface to port 80 via NGINX. There is a proxy device attached to it that listens on the ip-addresse of the container (port888) and connects to the

I can access this via [IP-addresse]:888 on the browser of my own machine but not from the browser of another host on my local network (a VM running on my localhost which can ping the [IP-ddresse] and also reach the interface of my local router via its IP.

Any idea what is going wrong here?

Please check you ip table if routing is proper.

can you specify what you mean here?

(I have a bridge btw)

$ ip a show lxdbr0

Please show lxc config show <instance> --expanded and ip a inside the container and on the host.
