Container Instance with openVPN does not run correctly - azure

Question

I am trying to run a Azure Container Instance with openVPN inside to connect to an external site. I have now managed to make a setup where I use docker-compose to handle the setup.
The container works when I run it locally (with openvpn establishing a vpn connection), and the Azure DevOps pipeline also builds and push to Azure Container Registry.
BUT when I try to run a Container Instance on the image nothing happens, and if I try to run my script interactively I get an error stating basically that there is no connection.
Does anyone have an idea of how to solve this?
My azure-pipelines.yml look like this:
# Docker
# Build and push an image to Azure Container Registry
# https://learn.microsoft.com/azure/devops/pipelines/languages/docker
trigger:
- main
resources:
- repo: self
variables:
# Container registry service connection established during pipeline creation
dockerRegistryServiceConnection: '*****************************'
imageRepository: 'getstatus'
containerRegistry: 'composeproject.azurecr.io'
dockerfilePath: '$(Build.SourcesDirectory)/Dockerfile'
tag: '$(Build.BuildId)'
# Agent VM image name
vmImageName: 'ubuntu-latest'
stages:
- stage: Build
displayName: Build and push stage
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: Docker#2
displayName: Build and push an image to container registry
inputs:
command: buildAndPush
repository: $(imageRepository)
dockerfile: $(dockerfilePath)
containerRegistry: $(dockerRegistryServiceConnection)
tags: |
$(tag)
- task: DockerCompose#0
inputs:
containerregistrytype: 'Azure Container Registry'
azureSubscription: 'Composeproject'
azureContainerRegistry: '{"loginServer":"composeprojectsrc.azurecr.io", "id" : "/subscriptions/*********************/resourceGroups/RG-ComposeprojectCloud/providers/Microsoft.ContainerRegistry/registries/composeprojectscr"}'
dockerComposeFile: '**/docker-compose.yml'
action: 'Run a Docker Compose command'
dockerComposeCommand: 'up -d'
In my docker file I run the following command which should make the openVPN connection:
CMD openvpn --config config/fremsyn.ovpn --daemon --auth-user-pass config/login.txt --askpass config/password.conf \
&& ["python3" , "src/cli/getStatus.py"]
And the docker-compose.yml like this:
version: "3.3"
services:
getstatus:
image: composeproject.azurecr.io/getstatus:v1
restart: always
