2 Foundry-Instance - shared data-source

[JuIez]

Hey Guys,
I tried to get 2 Foundry-Instance running with the same data-source.
If I put them to 2 different locations, there won't be any problems, but as soon as I try to get them to the same, I can't access the second one.

Is there a way to fix it? Since I use a lot of Add-ons and share maps between multiple worlds, it would be really useful.
Thanks in advance :D

version: "3.8"

services:
